Why on earth do you think anyone would rent out a house, or pay for all the ancillaries - furnishings, repairs, insurance, legal etc. if they didn’t get a return on their investment, time and effort? Do you also accuse Marriott of being parasites for renting rooms? Or Hertz for renting cars? They do these things because they spent a lot of money to provide something of value that people can utilize for a period of time but they still expect to make money.

Renting is a business. It’s as “parasitic” as any other business were a person pays for something with money and receives something in return. If you are not prepared to rent then don’t. There are other options to having a roof over your head. Buying a house would be one option but there are others.
