I understand "car" as an example, because lets be honest it is a great comfort, and having your own car would make things much easier. Depends on where you live of course, for example I have never been there, but they say, if you do not have a car at Texas, no matter which part, you would have huge trouble, because everywhere is so far from each other.
But if you have a car in Paris, that would be a trouble to HAVE a car, it would be smarter not to have it, because everything is connected with metro anyways. But if you needed a car, and it made your life better ,then I get it. The parts I do not get, is getting latest iphone, or luxury brand clothes, or most expensive tablets, or tv's, and what not. Things where the alternative is still the same thing. Like, if you don't have a car, you use public transportation, but if you do not use luxury shirt, you still get a cheap shirt, it's the same product.
