Because destroying a faction of the geth that the Orthodox geth allowed to seperate can be regarded as war. In that respect, there may be an idea within the geth that peace cannot be attainable if organics choose to destroy a faction rather than make peace with them.
Thus a consensus can form that organics do not want peace, and co-existance of Rannoch cannot be achieved by peaceful means. Thus war is only possible for organics reoccupy the quarian homeworld.
You can say that the rewrite was not a peaceful action, however, everyone can say it was non-violent. No geth "died". To bring the geth brothers together in a non-violent fashion, and making the geth more powerful, can, inevitably, be construed as a peaceful maneuver, and realizing that this was done by an organic nonetheless, the geth can build a consensus that trust can be built with organics and synthetics.
That trust can be the only way the geth and quarians can coexist.
That doesn't make any sense and the Geth gave Shepard the choice in the first place. Legion says you have to make the decision, if they're not happy with the decision later then it was their mistake. If the Geth are going to think the way you suggest then peaceful coexistence is highly unlikely anyway, they'll just find another excuse to go to war.

Admiral vas Neema says, "We need to find a world to shelter our non-combanants."
Admiral val Krois says, "We need to find out IF we can make peace with the Geth."
Legion says, "The Geth are 'caretakes' of Rannoch, and cleaning up the damage from the 'Morning War'.
This implies that, the Geth and Quarians are going to make peace and end their fight, Shepard tells them, "You BOTH need to end this war, or we'll ALL end up paying for it!" IMHO, when the Quarians find out that the Geth have actually rebuilt Rannoch and the other colonies, they will thank the Geth and return to their 'homeworld' to join Shepard and the Geth in the fight against the Reapers as allies and not adversaries.
I'm not sure the Quarians will exactly "thank" the Geth, they might be able to start living together though. The real problem would be that individual Quarians may not be happy and could lash out against the Geth, for them to continue existing together the Geth would have to be able to identify the difference between the individual and the whole (that does seem to have been a problem for them in the past, perhaps because they think of themselves as the same being).
On another note, I don't know if the Geth are actually keeping Rannoch intact because they want to give it back to the Quarians some day. It's possible that they're keeping it as a kind of memento (similar behaviour to what Legion displays with the N7 armour piece) or for some other reason. It's at least implied at one point in ME1 that the Geth have some form of religion (or at least are interested in looking into religion) so it could also have something to do with that. It's possible that the reason they're keeping it may make them less likely to want to give it back (they may think of it as theirs, you could argue that it is their homeworld too).
