I'm too late to vote, but not to say:
Very good post!
A portrait of JJR hang in Kant's studio, as far as I know.

What role does the sequence play - if it plays one?
Is liberty the topmost value, or is it just the starting point for fraternity to be regarded as the topmost one? Or do belong all three to egality, which in this case would be the topmost as well as the unifiying value of the triple?

In regard to the given citation of Rousseau, I'd like to remark:
Do we know if there hadn't been numerous trials of 'pulling out the stakes'? Again and again, but in the end...
Do we know if the first enclosing of land was against neighbours and not against beasts? And then was 'my' opinion that 'my' neighbour's fence or the fence of 'my' village was too weak and I built a stronger protection for my own since the community was not willing to follow my advices? And so, my fence was stable against beastly attacks, and in the end the others followed me as their guide?
(I think Jean-Jacques knew that this was a possibility, but he omitted this for stressing his own argument. And arguing is on it's own way a part of building guidances and fences...)
