That is the fixed amount of money idea. Money isn't an IOU pointing to an underlying physical wealth. It is wealth in its own terms that is created by government out of nothing based solely upon its future ability to tax. Even some bank money is secured on future income streams, although that is mostly discounting physical collateral.

There isn't a one-to-one mapping between money and stuff. Never has been.

"You're misunderstanding the term "rent""

I'm not. You're hoping I am.

The economic rent comes from the capacity to hoard. Once you remove that the economic rent is eliminated. In other words ownership isn't the root cause of the problem - it's the capacity to prevent use that is the problem. So you eliminate that by forcing things to be rented out and used, or they will be confiscated.

Which incidentally is a function of tax. Either you pay it, or you lose assets. So either you rent it or lose assets does the same thing.
