This is a great counterpoint, but you're missing the other half of the argument. The realm of subcultures that do not require one to change their material lives/location is far vaster than it has ever been. Perhaps the author is unaware of the seemingly endless array of niche blogs and forums and servers that cater to far-flung populations of people engaging in all manner of counterculture, some of it radically "counter", that did not and could not exist without the internet.
