Small-town midwesterner here.
There's some truth to what you're saying. Even the smallest apartment I've ever had was big enough to dedicate space to some serious hobbies, and it was (at that time) very inexpensive to rent compared a much smaller place in a more-dense area.
My lifestyle isn't very compact because it has never needed to be compact. Compactness isn't a common expectation 'round these parts. I have space to keep collections of stuff that I find interesting, and to make use of it.
There's tradeoffs to this lifestyle, though. The corner store is only a short walk away, but it mostly just sells beer, soda, and smokes. There's no walking to get something like groceries, or a new shirt (or a used shirt, for that matter). There isn't much for local entertainment. It's 15 miles to the next-largest city, and there's zero public transportation aside from the buses that get kids to/from school.
(It's hard to imagine that there aren't areas of the UK that are of similar form, though, with roomy housing, space for things, and with very limited services and/or options for commerce nearby.)
