I can relate with this. I only socialize for sex and/or money (e.g. networking). I have zero interest in anything else.

From my point of view everyone does the same, but can't deal with the isolating nature of it all and need to decorate it with friendships and similar unwritten rules and then act surprised when they don't work

"can't deal with the isolating nature" sounds like other people do feel a different need/reason to socialise no? People can pretend to socialise for one reason when really it's another, but people need to be interested in meeting this third need at least occasionally for the pretense to be worth trying.

Kind of, but most human relationships are somewhat regulated (marriage, parenthood, etc) so everyone has a framework on what to expect, do's and dont's.

Friendship is when everyone comes with a random set of expectations, all of them differing from person to person, and get disappointed when it doesn't translates to reality.

So you just don't grow friendships with people with incompatible expectations. It's not that complicated.

That's a remarkably sad, pathetic outlook, and one strangely contorted by Capitalism: Why do you want money?

That's the key here. Most people want money because, contrary to the old adage, money buys happiness. People want friends for the same reason: friends are the people who you are happy to spend time with. Pretty much any activity can be made more enjoyable when done with people you enjoy spending time with.
