This is completely backwards. SPS proposals are (if I understand you correctly) funded by default, and only not funded if enough people vote against them.

Instead, only fund those that receive that baseline of votes.

This mechanism is intended to tax the creators of the ~10% share of the rewards pool they split between them, by default, and is the most regressive taxation example I am aware of in the history of the world, not just Steem. The ~90% of rewards that go to substantial stakeholders via stake weighting manipulations, curation rewards, and bidbot profits, aren't touched. Not even the tyrants waging the centuries of war in history left the nobility untaxed in that way.

You should learn from those examples. Kingdoms vanquished because the nobles refused to fund their defense shortly thereafter had no nobility. I once owned Cram's Unrivaled Atlas of the World from 1911. When that edition was published there were 1000 princes of Russia. After 1917 there were 0.
