It's so radical that it's almost impossible to predict if it would be better or worse. But at least it had the moral ground that rent is one of the last remnant of pre-capitalist lords and barons economies.
The idea being it would commoditize housing. Millions of units would now be for sale, prices would drop, tons of people would now be able to afford buying. Home builders would be incentivize to build nicer, cheaper, as the competition would move entirely to the selling/buying market.
It's radical for sure, but I've always found the thought experiment fascinating.
