Many people have no interest or ability to take care of a property. I watched my grandparents' house deteriorate and literally fall apart from neglect. [I used to think the roof leaking when it rained was a totally normal thing] They had literally every appliance in the house break over the years but they didn't have the wherewithal to replace anything so they just went without. They lived in total squalor for years, it was depressing (as well as very dangerous) visiting. If code enforcement stopped by they'd be homeless.
For sure, there is many, many benefits to owning, I love being a homeowner (most of the time - though I did get a little sticker shocked at my first 4 figure repair bill), but don't believe for a second "everyone should own."
