> Why should Spain have any claim to someone’s assets in some other location entirely, especially for this type of retroactive wealth tax? It's the only (easy) way to make a wealth tax like this work. If you don't target total assets regardless of where they're held, dodging the tax is as "simple" as moving your assets out of Spain. You could implement complex "exit" taxes for foreign asset transfers and purchases, but a flat "we will tax everything you own, everywhere" is simpler.
