Property owners providing almost no value is just factually wrong. Their function is similar to insurance. You pay rent to live somewhere because you don't want to take the risk or can't get the loans to buy a property yourself. And it costs real money and time (i.e. real resources) to build those homes and maintain them.
In return property owners (or insurance runners) can get rich off your monthly payments as well as the inherent value of the property (/insurance company), but because of risk of ruin, opportunity cost for other investments and other related phenomena, it can mathematically be a total win-win for both sides.
What everyone complaining about property prices also always seems to forgoe are two things: First, people are clearly able to afford them or the prices wouldn't go higher. The myth that property investors buy homes on mass and don't rent them out which supposedly creates this pricing hike is idiotic. All of these big cities with insane rents have very low vacancy rates compared to the national average.
In almost all of these places where people complain about rent, we are talking about big popular places where everyone wants to go even though there are tons of realistic alternatives all around the country. The situations where it's economically totally necessary for you to move to an expensive place but at the same time you can't afford the rent is so rare as to be virtually non-existent.
Even the idea that people are displaced from their homes is an issue on a smaller scale than people make it out to be. That's because income in those expensive places is much higher than in cheaper places. There are people displaced from their homes, but that's because of poverty and other aspects of gentrification that are not necessarily tied to rent.
