I can't believe this thread is still going. In the end, if billionaires can afford yachts so big they need their own yachts, they can afford a wealth tax. If they can afford to create space companies to just have a pissing contest among themselves to see who can go further faster, they can afford a wealth tax. If they can afford to set up their own enclaves where they buy out all surrounding property just so they can have an unobstructed view of the scenery, they can afford a wealth tax. Literally, no one who is not wealthy is going to shed a tear because Bezo can only afford one Giga yacht. Personally, I couldn't care less about those who already have far more freedom than the vast majority of people, maybe, possibly, losing some of that freedom, and I highly doubt I'm alone in that.
