Working in a coworking space has all the problems of office working without any of the benefits.

I don’t need to be friends with my coworkers, but having non-scheduled interaction with them makes working with them much much easier. I worked on 3 different remote teams and I honestly don’t even think I could name most of my former coworkers, let alone recognize them.

It’s not about picking friends. It’s about building trust and connection with the people you are already spending all this time with. It’s hard to tackle big challenges with people you barely know and don’t trust.

Co working space? No thanks. That’s like a motel versus a home. They’re dirty and noisy. Our employer keeps a great office space with everything we need and no coworking space can compare. It’s also a permanent space we know after years of working there. And I’ll bump into more distant coworkers there just by chance. With co working spaces you basically have to plan specific days to meet specific people somewhere, and it cuts down on serendipitous connection.

My old company is a great example. They love to say collaboration and shit as a reason to be in office, but you need to ask your CO for permission to speak in office

While a co-working space would indeed help with having a separate work environment, I disagree that it would help with the social part of my problem with remote work. Not only do I feel far less like I am "part of a team" when I'm with a remote team, but often it leads to a lot of friction on collaboration in my own work. I'm quite headstrong and have trouble reaching out for help when I'm stuck with things, and part of addressing that is lowering the friction involved in getting help as much as possible. Idk, this is all anecdote and maybe isn't as applicable if you're not doing software development, but it's what I've experienced.
