This is wishful thinking. Billionaires can vote with their feet, or can pay expensive lawyers and accountants to find all the possible loopholes to not pay those taxes. California wants to tax Elon Musk for his trillion dollars. But how much of that trillion dollars was generated in California? He has a very valid claim that a lot of it was generated in Texas, and he'll go all the way to the Supreme Court with that.
People can vote that a new tax should be levied on billionaires, but can't vote how those billionaires will react to the tax. Moving out of state is one option (see Larry Page, Sergey Brin, etc). Hiring armies of lawyers to challenge any wealth assessment is another. Litigating to the Supreme Court yet another. I'm not a billionaire and never will be, but if I can think of these few ideas, they can think of 100 times more.
Exactly. You can ask many things, like you can ask for world peace, and you can ask for universal brotherly love. If the ask has no chance to result in the outcome you desire, it's purely wishful thinking.
It feels to me you are asking "why can't we just eliminate billionaires". Well, they have a vote in that decision.
