I've put in a suggestion in this thread about Land value tax (Check out my comment in the link below). It's a progressive wealth tax and works just fine in cooperation with the crypto world. It leaves crypto alone since crypto uses very little resources, but taxes physical land use which is the ultimate limited resource.
The wealthy elite also happen to own the most land.
It also works great for automation. Automation itself is good for society (less labor for humanity), but the profits used to hoard valuable land by the automation owners will be taxed. Profits that are reinvested into productive assets are not taxed.
