The point is that paying rent is fine as a temporary solution, but it doesn't give you a place to sleep forever necessarily, even if you have the money to pay for it.
That's true, but some people still prefer to keep paying rent until they pass on, I know of someone like that in my region, he was paying rent till he pass away, he didn't build or buy a house for himself. Personally for me, I feel it's necessary that at some stage in life, one need to have their personal house that they have bought or built for themselves. Buying a house is quite expensive, so, renting is just like a temporary solution to have shelter but if one has enough money later to get a permanent home, it's better off.
