From your many post throughout the thread, it doesn't even sound like you want to be a neet, It sounds like you want to be a self-employed artist of sorts. You could probably make your neet-ajacent lifestyle wants work by having a few self made/published games on steam or a crowd supported art project be it a web-comic, patreon porn nonsense/commissions. (I am slightly assuming that cost of living expenses in Thailand are relatively cheaper than the USA, which should make things easier for you to do, feel free to correct me if I'm wrong) You might also be able to take advantage of the whole V-tuber thing if you're a girl(doubt, but there is always a chance), since you have programming/art skills you could make and rig your own model to siphon money from thirsty simps while you play games, you even have experience manipulating people through your current job so you should be able to find a niche in the field if you try. It looks like you already have a plan to work towards this in finding a part time job to subsidize your art stuff, till it makes enough to live somewhat comfortably without it.
As for the neet vs other side of the equation, it seems the isolation and repetition grinds against the soul of the vast majority of people, slowly draining the motivation to even do neet things as your life spirals into true pointlessness. In addition, if I may armchair physiologist for but a moment, your overall negativity and dislike of societal norms in cross reference to other post that I have seen you make comes across as sour grapes towards what you perceive normies as having. The general feeling of acceptance, lack of care, and I suppose, feelings of happiness.
In order
Sex is something that people have a tendency to hype up due to both it's pleasurable aspects and , for males, as a symbol of success, but as quite a few people have figured out it's rather hollow by itself. It's ultimately the intimacy and bonding with another person that gives it any real value.
Starting a family has traditionally been a struggle, it's really not any different than it has been for the past 1000 years or so, though the swing from good/bad times isn't quite as severe as it was in the past. I actually don't find the world to be dystopian currently, just in a period of transition since it has basically reverted back into early stage capitalism on a global scale, and it's gunna be a while until things balance out. I also don't understand the general negativity around existence since life has been far, far worse in the past.
As far as socializing is concerned, you seem to be doing just fine here, online spaces are just as much a form of community as anything else, you really shouldnt hold in in lesser regard. The internet hasn't quite been ruined yet, since normies make up the majority of people of course the largest, most popular places are going to be normie spaces. Places like Agora Road still exist for all manner of niche interest and, at least for now, it seems most normies don't want everything non-normie to be kicked off the internet. In addition, I don't know how you could tell that there is no real community where you live since you actively avoid participating in most social activities, also
I imagine you hide your power level while preforming your job, most non-normies do that when interacting in a public business, you likely wouldn't know it even if you had interacted with one.
