This is already happening with property ownership being coagulated in cities. How is this a surprise
It's as if you bought your house, but had one room walled off with the developer saying "for only $100 a month, we will open that room up for you! isn't that great? you only pay for it if you need the extra space!"
Except that obviously the room is there whether you pay the subscription or not, you paid for it in the cost of the house.
You are assuming demand is equal for all of those. It might be in some places, but not others.
