mandatory voting is not something i agree with.

The house and senate should both exist, they both serve a purpose. The senate gives every state an equal footing, the house gives every state representation in regards to population, so they both serve a very explicit purpose.

idk about house rep cap. There are already so many, perhaps improve the makeup of the reps though? That's pretty messy.

on the supreme court term limit, include an age limit as well.

That's it, everything else would be fine probably?

UBI requires such a large reorganization of the economy that you may as well add democratization of the workplace, and it would get done earlier. I think both would be great personally.

Prostitution will just objectify women

What's wrong with filibuster?

Can someone explain to me what "collateral for loan is realized gain" means?

I like where you're going here, and the only things I disagree with are the Senate merge and Electoral College as these still serve a purpose. The removal of the House cap will rebalance there, and if anything the Senate could be reverted from popular election back to being appointed by the State Legislatures so they rebalance back to being actual actors for the State as intended vs overpowered Representatives.

The Electoral College helps balance democracy being 2 wolves and a sheep voting on what's for dinner, but maybe get some math experts to review the equation for apportionment and/or set all electors to be proportional to the vote percentages in every state.
