Infringing on human rights of the rich people is one of the worst things you can do for the economy, because they are the people with means of production, and they are the people with options to go somewhere else.
The premise that you are free to make as much money as you want and not be punished for it is one of the biggest things that made USA awesome in the first place.
The idea behind UBI is that we can now afford it because we have abundance of resources to support it. If that were the case, these resources would be available without the need to coerce people out of their money.
The only way to get those resources without taking away the freedom is to treat UBI as what it should be - a charity. Only when there's so much abundance that people are willingly giving away enough of their money to support everyone else, when it's a choice and not a coercion, will UBI have a chance at working without creepy and horrifying consequences.
