I don't get it. What if the person doesn't want to sell at all? Self-value at +inf and pay 1% of that?

Society has already decided that we can compel people to sell their private property for fair compensation via eminent domain. Plus getting the assets in the hands of people who value them more certainly creates utility and presumably increases the tax base via further development.

This type of forced sale happens all the time with public companies. For example, only like 60% of Twitter shareholders approved the sale to Musk, but the other 40% were forced to go along with it regardless of their preference. If Musk can do that to other people, why should some hypothetically richer person not be able to do it to Musk?

And to repeat myself for a third time, we don't need to haggle over price. If we only want this to apply to billionaires, assets worth $50 millions, or whatever, that's fine. If one of the people impacted truly doesn't want to sell, let them set the price as high as makes them feel safe. I'm not going to lose any sleep over taxing the emotional desires of billionaires.
