He's comparing renting Vs buying, your comparing renting Vs living on the street. Makes sense. Lolthat is like saying you don't see the point in buying food or paying for electricity because at the end you hsve nothing to show for it.
The gain from paying rent is a roof over your head.
I also don't see renting as an option personally, I see it like this at retirement my house will be paid for and I'll just have the running costs. If I were renting I'd still have those running costs plus rent.
Obviously with renting you don't have the expense of things like boilers and plumbing, bit those are a fraction of the extra it costs to rent. Round my way renting typically is at least double a mortgage for the same property.
