Do you remember that MMT thing? That thing that says the government can create as much money as it needs and if there is inflation (doesn't matter if CPI or not) then you tax the part of the economy where inflation happens to return the money.

A wealth tax on deposits and land would be ok. The rich can buy bonds or stocks if they want. If there is a shortage of companies you can always create new ones. If there is a shortage of money or land it's much harder.
