"It's pretty much impossible for a billionaire to "consume" their fortune" So what? If someone uses some tax loopholes and then buys a few exotic cars, I can work up a little outrage about that. Maybe get mad about the loophole. Same if they are hoarding a bunch of stuff -- empty apartment buildings or something. But if they had to pay $1M for a Ferrari, and $900K of that was taxes that I might benefit from, it's hard for me to maintain that outrage. And if they had to pay 1000% tax on that empty apartment building (nobody else is using it, it must count as consumption, right?), then that could make a sizeable tax payment. In fact, this is starting to sound better and better. Anything not being rented out counts as the owner renting it, and paying consumption taxes. That'll get more stock in the housing market, fast. Probably need to sort out some accounting about how to treat depreciation vs renting vs buying. The main point is to tax people for consuming or wasting stuff.
