I think the fundamental misunderstanding here is that your assumptions are based on not understanding how policy works in the real world. All of your strawmen problems have already been addressed and they're not serious issues.
What you've suggested for getting around the wealth tax amounts to various forms of tax fraud. That's a crime punishable by many years in jail on top of having to pay the tax avoided, plus penalties, plus interest. Most people aren't Wesley Snipes, and they're not going to risk their freedom to pay taxes. If they really don't want to pay taxes, they'll do what a number of French people did when the wealth tax was first introduced: they'll move to a country without a wealth tax.
(Also: courts can issue withholding orders, stop payments, etc., to domestic counterparties under their jurisdiction. This is a tried and true remedy that's been around longer than either of us has been alive.)
