Every Hive proposal gets funded?

No? So the proposals are put to a vote?

What about the ones that have value but not enough votes?

People with one person one vote will in the main vote for what seems most likely to profit themselves or favors people in their tribe. It becomes "fair" only numerically, not in terms of outcome.

That is why we need something to counteract that force. Find a way to fund things that are necessary but not popular.
