I'm not quite sure where you're getting that there's no elbow room in space.. the biggest reason they'd be used up there is because of the launch cost as well as ease of repair.

The other guy was probably talking about cost per unit of weight.

Yes, absolutely correct. Both weight and size are considerations for payload.

Yeah but saying that "there's no elbow room in space" is such a weird way to word it to the point that it becomes misleading. There isn't, as far as I know, a misconception about the amount of room in space but comments like that are how those misconceptions are born.

Launching stuff is incredibly expensive, so you can’t afford to have a whole room just for elbows on a space station.

This is a good point. I was meaning as payload. The amount of cash necessary to take a unit of weight up is otherworldly. ;)
