I think the author's point isn't that it's easier, it's the fact that being in an isolated, low judgmental environment allows you to express edgy ideas more uniquely without the prepackaged style you often find in big cities, where fashion brands and think tanks have heavy interests in selling you the next big thing.
A good example in Europe is how Berlin went from being a cheap city with loads of artistic freedom to a place where people wait in line for hours outside a club just to find out if their black leather shirt is edgy enough. They're all trying to stand out, but somehow they all end up looking the same.
