What of people who can’t or don’t want to afford to buy and maintain a property? Several times in my life I benefited from renting a room, apartment, or house (in college, just after college, after a breakup/move out, moving to a new city with an unstable job).
It would have been a massive financial burden and personal inconvenience if I had to buy/sell every one of those times.
The probability of an average person being able to afford to live in a home in a "nice area" is much higher in Sweden and other countries with rent control than in countries without. There is no shortage of homes, there is a shortage of homes that people can afford.
