One account, one vote (1A1V), sounds good in theory

No. It sounds a lot like socialism. It creates an injustice. A disincentive to earn/invest in the token.

A good theory is a theory that works in reality. Capitalism is where economic power flows to people who are productive and make the most money. This is an ideal. "One economic unit one vote" is the ideal.
