The article states that "owning" is not the right solution for everyone, but what it omits to state is that in most of those countries where the majority of the population can afford to not own a home, their social security takes care of individuals once they reach the age at which working to fork that rent out is not possible anymore.

In the US, that is not currently possible. So the solution indeed is to buy a house and hope that by the time you reach retirement and cannot work anymore, you at least have a home and maybe the tiny bit of money you were able to save will suffice to pay your bills and food.

The solution in the US is not to fix social security and ensure those who rent today will have enough to rent when they retire, it is to reduce the cost of home ownership, so by the time you are 65 you already own a home you can afford to live in because you own it after only 15 years of hard work, not 30+.
