Well, maybe you should have taken a look at housing prices in California. People are willing to pay $2 million or more for a house in SF. That's quite a bit more than "free".
The only people whining and wanting things ”for free” are the rent seekers who sought to eliminate property taxes so they could impede economic progress and live for free and try to prevent anyone else from moving in because “muh soul“ (translation: “muh property value”)
Correction: you are right, "market rate" implies free market, which means free from government intervention -- which is very much not the case when it comes to housing.
Would you be ok with private owners being able to buy up all your water and only selling when they want to at the "market rate"?
If speculators can buy up all the available property, why not allow them to buy up a region's drinking water too? I'd be the first to jump in and get massive loans investing in it. When it all dries up and no one wants to sell, will people be cheering on the free market here?
