Some good ideas here, but I don't see that it would get around the money problem - "I'll give you $$$ if you delegate x of your points to me" - before you know it, those with money are again calling the shots
You are right -- In this aspect, the new system is not an improvement on the status quo.
What prevents someone from saying - "I'll give you $$$ if you vote for X" ? The Law, that's what. It'll be illegal to buy points, as it is to buy votes, which is a deterrent ( hopefully ).
If anyone can innovate and improve this aspect of the voting mechanics, I'm all ears.
Actually, I'd like to backpedal a little.
It is relatively cheaper for a corporation to lobby/bribe an elected representative to get a particular outcome on an issue. Also, there are very few people aware of this violation of law, so the crime is less likely to be caught.
It's a lot more expensive to bribe a lot of voters to sell you their points, without this violation being noticed.
