There are tons of hiking trails around Belgrade (if that is really his location) and he could even bring podcasts and a headset so he does not even have to leave the content-drip of mommy internet.
Josh continuously sits on a high horse, shitting on people who are unemployed, addicted to drugs, mentally ill, et cetera, yet cannot even muster implementing the habit of going outside *just a little bit* to invest in his health.

Even Ralph would not be childish enough to suggest something as dumb as that, even Ralph goes outside sometimes, trying to make the most out of his shitty situation of being stuck in a foreign country. At least the gunt has seen some cool parts of Mexico, been to Rome, been to Portugal, without sitting in a shitty ass hotel all day long.

If I wanted to become an off-grid self-sufficient person, the very first item on my ToDo-list would be to make sure that my health was good enough to actually handle the physical labor intrinsic to any such undertaking. Nerding out over which gun-streamer to follow would not be anywhere near the top of my list.
