Honestly that is a silly argument. In any system of votes if you multiply everyone's votes by 2 or 10 or 1/2 or a million, everyone still has the same share of the votes.

The multiplication does not do what you claim.

There are good reasons for approval-type voting in this context which have nothing to do with the founders wanting to have had complete control. In fact, originally the founders had a much larger share than Tron has now, and probably would have had complete control even under the system you propose.

What you are trying to do is give more influence to a distinct minority stake. That's laudable in some sense, but you can't avoid recognizing that weakens the security of the chain, which relies on: a) the majority being honest, and b) maximizing the threshold that a dishonest minority much reach in order to gain influence.
