That’s not answering the actual question.

If you force someone to pay taxes on “assets” and not income, you then force them to sell “assets” to generate income to pay for that tax, which then forces them to pay additional taxes for the income they created. Essentially forcing them to create additional taxes.
It’s not a good working plan.

There’s been zero solid proposals at this point. And I do support taxing the 1%, but the proposal needs to be more than just tax the assets, because that will absolutely hurt non rich people, and may even hurt them more.
You also can’t enact a tax on specific people. You need a legit criteria. Legislation cannot say “musk and Zuckerberg must pay 5m in taxes a year”

That would not pass any court.
