Disagree, and I'll quote you to explain why:

Then, after some time when system reaches some balance, check if your desired proposals are on top, and unvote return proposal until your all or most of your besties are above it [emphasis added]

This can't be done when the only choice possible on a huge account is 100% or 0%.

For the system to work properly people have to be able to vote not just yes or no but also on the specific ordering of proposals, and people with large accounts can't currently do that (other than by splitting their accounts, which is generally undesirable).
