And B, even if you wanted to live that way you can't any more; because the commons has been relentlessly exploited past its breaking point for centuries.

In many countries the only obstacle is the legality of living on government lands. In Canada there are people living a nomadic hunter-gatherer lifestyle on crown land. The option is totally available for many people who chose not to do it.

Yes, the obstacle of living illegally on land that has been systematically over-exploited for centuries (or too harsh to bother), without any community or experience. Not sure I'm seeing your point.
