Am I naive in thinking that we haven't expanded into space because we don't need to? What's the benefit?

Asteroid mining is the obvious one. That said as part of looking into SpaceX's business I learned that currently the TAM for launching other people's stuff into space is under $10 billion. SpaceX already owns most of that market. Their own focus on data centers in space IMO speaks for itself.

For why we'd want to go at all: there's a lot of resources up there, and pollution is much less of a concern for factories made up there. Also some material processes may be much easier in zero-gee.

But that doesn't mean it's actually worth the effort.

Access to resources. A sense of adventure. Learning.

A hedge against civilization-destroying events. Meteors, global war, disease.
