I'll just run with "being elected Divine in the first place" even though I'm not sure I can really blame her for that. Well, I guess I really can, since it smacks of manipulating really desperate people enough to get a Mage ruling over people. I'm wondering if Eamon is considering putting Connor on the throne now, and if Viv will have any objections to another mage ruling over man?
And what, exactly, is wrong with being elected Divine?
Unless you're the sort who believes that mages should be disqualified from any power by blood, being elected by mundanes- the same mundanes who otherwise elect Casandra or Leliana- is about as good as one can hope for. Vivienne is not being made ruler because she is a mage. She is not inheriting it to continue a dynasty. And she will (presumably) not be handing it off to a child of her own.
The danger of magocracy comes from the oligarchy of mage interests being prioritized. Vivienne, isn't.
Despite how true everything you say is, I think you are slightly misinterpreting what some of us mean when we say she's "outside the system". We don't mean the Circle system overall--she has made it clear that she actively participates in its higher tiers. We mean that she is far removed from the 'average' mage and their lifestyle that it is highly dubious as to weather she can properly comprehend the issues within the Circle system seeing as she's so above them all in terms of position.
Perhaps at one point she could easily relate to her mage peers, and indeed she can still rightfully claim that she does relate to them in a certain degree still. But by this point she is all but laden with (rightfully earned) privileges to the point where her circumstances could hardly be called typical of a Circle mage.
So what? Where does this argument end? That because she's obtained power, she's illegitimate and knows nothing and her views are inherently wrong because she magically forgot the same foundational experiences all her peers had?
How can any authority figure claim to by 'typical'? Leliana, the Orlesian Bard and spy master of one of the more influential groups of Thedas? Casandra, professional thug for a more moral sort of ruler? Do they live like the typical people? Share the experiences? Has Leliana ever lived in an Orphanage, survived with the Carta, or ever truly been weak for much of her life?
Where she can reside in villas and other housings outside the Circle proper, most mages are relegated to staying inside only the Circles. Where she can openly and confidently mingle with non-mage populations, many mages are sequestered to where they only have other mages for company. Where she can walk roads and streets without Templars on constant patrol, many mages have to deal with Templar scrutiny for virtually every hour of every day. Not every Circle is that bad, of course, but it still stands that she is all but removed from the typical culture that makes the daily live of the average mage.
The average mage can work towards such freedoms and privileges, because the system does allow you to earn them.
You don't need to be a Court enchanter to do so- though you could try, if you were willing to take risks like Vivienne was. You can be like Wynn, or the botanist, or White Spire mages who were allowed to go shopping, or the retiree who got Shale. Even in Kirkwall, worst of the worst, Bethany can attend some of Hawke's adventures.
We can certainly say that the average mage doesn't get enough of these opportunities- but you'll be hard pressed to find Vivienne arguing against that, and with power she certainly expands the scope of their opportunities in ways that even Leliana doesn't.
The claim of hypocrisy mostly comes from how she claims that mages are being unreasonable in trying to obtain certain freedoms while she herself already has those freedoms. Freedoms she earned/politically maneuvered for precisely because the Circle system was so stifling to her.
Then people claiming hypocrisy are using the wrong word at best, and deliberatly misrepresenting Vivienne as worst.
There is nothing hypocritical in Vivienne's criticisms if she abides by the standard she set. Since Vivienne's criticisms come largely in how the rebel mages go about their rebellion- and she doesn't not do the same thing in the same way- there is not an inconsistency. Vivienne's position is not 'shut up and be happy with what you have.' She never tells people to not work to better their prospects. She criticizes them for disregarding the views of others (which she abides by her adherance to The Game), for putting emotion over sense (which sees the mages end up as they do), and for being woefully indisciplined (which they are).
Nor does her being a success story render her irrelevant to the typical mage- rather, she disproves the opposite, since she's what the typical mage could be because she started from the same. Vivienne is dangerous to the people who claim that rebellion was necessity because power, privileges, and freedoms couldn't come from within the system. Vivienne is a disproof of all three- that the mages can gather political power, that they could gain privileges and freedoms by playing within the rules, and that they don't need to overthrow the system to do so. And, if she gains power, she continues to demonstrate that.
Conservatively championing the old system immediately after it fails in every way possible is how I would have put it.
Hardly every possible way, and hardly disproving the old ways. The mage rebellion was a significant event, but also a flop- within a few years, a continent-wide uprising was soundly beaten and hiding behind the walls of its last protector as peace talks were under way. The Mage Rebellion was over and it's fate was back under the influence of the Chantry and the Kingdoms, no matter how the Conclave talked. Either the Mages formally surrendered to the Chantry, informally submitted to Ferelden, or they were put to the sword.
Considering how often uprisings and rebellions occur historically, the Circle system's design, even in its worst-case crash, was largely self-correcting and self-containing.
Moreover, Vivienne's conservative isn't stasis of the contexts that broke the Circles- she approves of reigning in the Templars, and reforming the politics.
