In my opinion, this kind of frugality happen when you have a small (or non-existant) social circle. The main reason to spend (clothes, cars, etc..) is to impress the people around you. If they don't exist, you are not that much pressured to spend.
This describes me though I have a reasonable social circle I pretty much don't care about any of the things on your list.
I rent a flat (apartment), I only own jeans, t-shirts and pullovers, don't own a car, own second hand (but good) furniture.
I'm trying to remember the last time I spent over £50 on anything that wasn't a gift for someone else and I really can't, perhaps my weight set about 18mths ago.
I'm just not attracted to stuff or to signalling via it.
