Fine. And whatever device you're using to post here just happened to emerge spontaneously from the dirt, instead of being built by the efforts of thousands of people spread all over the world as part of a modern technological society.

Also: where do you get your food? Do you grow it? Or hunt for it in a natural wilderness, untouched by technology, using tools you made yourself, without the benefit of modern technology?

Where do you get your clothes? Do you make them yourself? Out of natural materials that would be there if our modern, technological society did not exist?

I'm going to make a wild guess that the answers to those questions are "no"--that you are relying on sources of food and clothes that also require a modern technological society. Not to mention transportation and whatever else you need to do the things that occupy your day.

So no, you are not living a hunter-gatherer subsistence life. You are taking advantage of the fact that it is possible in a modern technological society to be a homeless bum living under a bridge, without having to do all the things that actual hunter-gatherers living a subsistence life have had to do all through human history to survive.
