Sure, and I can buy a gun and never shoot anyone or even try to in my life. But there are safeguards in place when buying many firearms.
It's not at all a slam dunk that such laws are a good idea. In the US at least it's somewhat contraversial. There is a significant percentage of people in the US anyway that feel that if you outlaw guns, only outlaws will have guns, and you can make the same argument for magic. In short, if someone abuses magic, then the authories (which almost certainly would include fellow mages as well as warriors with templar-like training) could and should come down on them especially hard. But don't punish people for what they are.
Same is true here - mages can be extremely destructive when they want to be. Much more so than one person with a knife. Besides, by that reasoning, Wynne - who set someone on fire as a child - should be locked away for life. Uldred, who so far as we know did nothing before his failed insurection, would be walking around free.
Wynne set the kid on fire as a kid arguably in self-defense. Had she thrown a rock and injured the other kid, the parents might get involved but even ina midaeval society, it wouldn't go beyond that (unless the other kid was a noble of course but that would apply equally to any commoner). Again, I'm not seeing it. Other cultures with magic don't seem to need to do this.
Connor should have been walking around free, too - and that turned out well. 
That was directly due to the malfaesence of both Isolde and Jowan. Isolde for hiding her son's talent and Jowan for setting up Conner in a highly stressful situation where he was especially vunerable to demonic possession (by poisoning his father). Conner was set up to fail almost as directly as those mages that have a demon directly implanted as part of their harrowing, and Conner (unsuprisingly...he was only six) was not prepared to handle it.
As for nurturing - Wynne seemed to like it there. Those kids we see in the beginning of the Broken Circle quest didn't seem to mind it so much. Neither did the older ones we saw with Wynne.
Wynne is a fundamentally sad, and broken down person, who has been defeated by the Chantry. Therefore she thinks that others should accept that defeat as well.
Some will like it, some won't. But when someone has the potential for unlimited destruction, shouldn't we keep an eye on them before they do something terrible? Because finding them after the fact may be hard, and too late for those they hurt.
Sure but keeping an eye ==/== torture and lock away for life
In fact I am of the firm opinion, that the circle-tower system makes mages more vunerable to becoming abominations because of the hatred it generates on both sides.
