The closer you can get the government to the people, the more they can be held accountable

by what metric?

any argument you can make for it being easier to justly oust them from power can also be made for it being easier to unjustly keep them in power

That’s why the power should flow upward, not downward

while a lovely, pithy statement, this has absolutely nothing to do with your argument, and doesn’t really mean anything in this context
