Perhaps it's a stupid question, however having never worked a day in my life I feel this feeling is no different from the existential dread of the inevitability of growing old and dying. Just as if you're severely balding or have some kind of terminal illness, there is quite literally nothing one can do to prevent it. As of now I can only feel numb to the fact.
>Question: How can one manage to survive as a hikkikomori? Answer: Because one's food, clothing, and shelter are often assured regardless of situation. In today's society, as long as you're guaranteed the barest essentials, you can continue to live out your hollow existence indefinitely. I didn't realize it before, but in a way, being able to live as a hikkikomori is a luxury. Without the assurance of food, clothing, and shelter; unless you're prepared to die, there's no other choice but to work.
IKTF. Everyone is an artist until they have bills to pay. I'd love to work exclusively part time or freelance doing what I like to sustain myself but that's wishful thinking, and it won't give me enough money to survive when I'm old. My will to 100% dedicate myself to my craft is simply not there due to the urgency to pay dues. I could embrace a quasi-bohemian lifestyle, but I value solitude and silence too much, don't have friends who are into that (contradicting to the former statement, IK), and I don't have a safety network to bounce back into in the case things go awry. And I'm also simply bad lol

If this is a literal question, you just mooch off whoever you're mooching for the longest time until you're forced to work at an older age. You better have built up some kind of meaningful skills or some kind of nest egg so you're not forced to work at 60. If you inherit property with no mortgage to pay, its very easy to live a low-cost life working a part time job, especially if you become a r*ntier.
To LIVE, however, you have to truly work. Not work for money or commodities, but work for yourself, do something you will be satisfied with in the future. A personal project, a skill, language, etc.
Work itself isn't bad, all life is work. It's just the forced socialisation, alienation (arbitrarily sticking around even though you're doing nothing, not doing what you minimally have an interest on, etc) and the sheer numbness and staticness it encourages, especially if it's a low skill job, that most people hate. Good luck forming coherent memories and experiences when you're just looking at the wall to clock in hours while listening to unstable people doing community service talking to themselves 50h a week, that kind of thing.
Of course being an hikki is a luxury and it is hypocritical if not achieved at it fullest because you're just leeching on the society that you despise and gives you the bare minimum to survive in it just so they dont have your suicide on their weak consciousness… The only way to be a non hypocritical and still be a neet is by being a chad hybrid hobo/hermit who lives off grid…
