My advice would be do all you can to not be poor. Being incel is hell, but being poor and incel is just doubling your suffering. I'm not advocating wageslaving either, because you want as much free time as possible to cope with enjoyable things like video games and taxes directly subsidize the system that keeps us all oppressed. Taxation is theft anyway.
If I were young again and had no business / career, I would certainly get involved in drug growing and dealing online combined with crypto. Its a new high tech age, you could easily operate as an anonymous online weed seller and be untraceable. As long as you didn't get excessively large and kept your grow sensible, and avoided areas like hard drugs, firearms etc, the feds wouldn't care.
Weed can be grown with LED grow lights now which emit virtually no heat, so the only way you can get caught is if you are stupid enough to tell people or you let the smell out because you are a HVAC pleb. Ship your product via private courier on a fake name account, receive payments via cryptocurrency.
