If a person misses social contact then there is a really really simple solution to that. Unless the OP is currently in prison they should get off their arse and step outside their home and just start meeting people and talk to people if that is what they want. It worked like this hundred of thousand of years ago and it still works the same way today.
That's why places where people freely socialize sell massive amounts of alcohol, alcohol reduces inhibitions and I imagine the stress level of interacting with someone for the first time.
Most life partners come from (frequently forced) proximity, same for best friends: kindergarten, school, university, workplace, etc.
Pontificating about what people should do doesn't help with what people have actually been doing for hundreds of thousands of years.
As it happens, I spent most of the year on the beach with zero regrets whatsoever.
Enjoy your WeWork.
You don't have to be the sad lonely remote worker if that bothers you so much. Remote work has definitely HUGE advantages allowing people to find a much healthier work life balance and has undeniably a net positive effect in comparison to what we had before, but I agree, 100% remote and never stepping out of your house again and meeting other people is NOT healthy at all. Good news is, nobody forces you to live like this though. I have signed up for a co-working space where I live. WeWork offices are littered around the world. It costs only $199 or something like this to get a flexi hot desk where you can go to any WeWork in your country. I go into a co-working space at least once or twice a week. I sit next to other people who also work and we chat, socialise, we still play ping pong during our breaks and we stroll out to a pub afterwards. Most co-working spaces even organise weekly/monthly social events which makes it even easier to connect with other people.
If you feel isolated because of remote work, then it's not because of remote work, it's because of your own choice to not help yourself. It's like a child crying that their trousers are wet after repeatedly pissing themselves instead of going to the bathroom.
