How do you plan to force people to sell? Maybe I’ll just let my kids/nephews whoever live there rent free. No one is robbing none of anything and in my experience, the mom and pop owners usually offer better rent prices.
Not to mention forcing even those who do somehow have massive amounts of cash or go into major debt to lock up all of that in an asset that historically underperforms productive investments (stocks), and putting their entire net worth in a single asset with no diversification whatsoever.
