I find it much harder to do any type of photography in the USA where it's hard to find places to walk around. And if you do find a place to walk you'll end up in strip mall, a parking lot, a multistate chain.
Just take photos of strip malls, parking lots, and multistate chains then. They'll look great in 40 years, like William Eggleston or Stephen Shore's work does today
I can certainly understand the sentiment - most parts of most towns are like this.
But if you look, virtually every town of reasonable age has a walkable "downtown" area. Even in small Kansas towns - look at downtown Ottawa, Seneca, Lawrence, etc. Or, across the country - Rock Hill, Greenville, Savannah, Tampa, Orlando, San Diego... The only ones that lack walkable downtown areas are the most recently constructed communities (Nocatee, Florida comes to mind - recent construction, the "town center" is effectively a strip mall).
