Did I say mandatory? I meant optional! You’re “free” to die in a cardboard box under a freeway as a market capitalist scarecrow warning to the other ants so they keep showing up to make us more!
Sure, but this shouldn’t apply to everybody. Unrealized gains up to $10 million don’t get taxed. Unrealized gains over that amount get taxed.
If you pay it yearly you’re not paying this every day. People with this much money almost always go up in unrealized gains every year, so it’s not going to be a back and forth. It’ll be a yearly adjustment. No different than literally everybody else that pays taxes on their new wealth every year.
Edit: as for the baseball card example, if you’ve got over $10 million in unrealized gains on baseball cards, yeah, maybe you pay taxes on that.
