I totally agree with you that I don’t need to make friends at work. I 100% clock out at the end of the day and make a hard cutoff between personal and work life. I can even work with people I personally dislike just fine, as long as they’re not making things harder for others.

But OP was talking about camaraderie, which is mostly just about being generally pleasant to be around - as Merriam-Webster defines it, “a spirit of friendly good-fellowship”. Nobody likes to deal with the moody guy who doesn’t want to talk to anyone either. At the other extreme from what you’re describing, one starts leaning into “making things harder for others”.
