Also, this dream ends the very moment you need an hospital. Hospitals are complex structures that require immense amount of resources to operate. Not not mention the resources needed to develop drugs, train doctors and so on.

Maybe you could live a solitary life, on your own, using only what your land provides you, but there's no way you could access modern health care, then.

Same goes for Internet access (all those subway cables were laid by somebody, probably subsidised by some government, at least partially).

Same goes for roads, and so on.

This is a myth very few people could live because the others don't and one way or another support them.
