Supply and Demand are only part of the factor, they orbit around Value. What determines the price of a commodity when Supply and Demand cover each other? The answer is Value.
Yes and renting of houses pretty uniformly exists under all market conditions I.e. even when supply and demand “cover each other”. So by your definition there must still be some value since it has a place in the market.
The value offered is a service, just like a hotel room. What is an alternative to renting that could enable someone to have a place to live without having the capital to buy property?
Isn’t this an argument that could be applied against communism though? Communism is government regulation to enforce fairness, if it can’t fix capitalism, why would it work in a communist economy?
