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.

People do it so it's definitely possible. Most people chose not to do it because it's a hard life with a horrible quality of life. Being a hunter-gatherer and living a nomadic life is not and was never easy or fun.
