Disagree, sure you can make more in the open market over time by getting another mortgage on a paid off home.
But that invested money means absolutely nothing if the market has a downturn and you lose your job. Now you’re on the hook to a mortgage you can’t pay and risk losing a place to live.
While on paper you can make more money, it’s very dumb to gamble with things you need to survive. And that’s all any loan is, a gamble that you will be in good health and have the means to pay it back.
And that’s the difference. Here you just get to be foreclosed on.
So yeah with having reasonable social safety nets in place the idea is a lot more reasonable
