I've worked for myself for 20+ years, but always in a shared office or co-working space which addresses any social side of a regular work environment. But, like you, modern/collaborative programming or project work has passed me by and I suspect I'm unemployable now. I think beyond the ability, there's also the interest/willingness in working for someone and it likely doesn't marry well with the fierce independence. I don't think I could do it now.
Thankfully, I have no intention of getting employed, so it's a reasonable stalemate; I just carry on working on my various projects.

You’re not missing out on anything. If something you’d be unpleasantly surprised how convoluted team work and new pipelines have become. Being independent is a healthy path to keep away from toxicity. But I agree about the unemployabiloty nagging feeling, it’s psychologically unpleasant to feel that but should you ever reenter the corp pool you’d hate it with all your guts.
