SpaceX craft overshot Mars’ orbit and is headed to asteroid belt

As long as we are just sending satellites up into LEO that takes far less energy than you might think. Flying around the world or getting to space are not that far apart. SpaceX for example is only worth ~20 billion because there is simply less demand for rockets and they cost less than many assume.

Now, if we want to colonize outer space then asteroid mining becomes necessary. But, with current tech there is little personal benefit to being in space vs staying home.

PS: I am not going to try and predict what happens 1,000 years from now, but space is unlikely to be a nice place to live any time soon.

Even short of full colonization sourcing materials from space will allow much larger structures and shapes that would be difficult. Ultimately right now we're severely limited by the fairings, inflatables like Bigelow Aerospace solves some of that but ultimately there still limits to the volumes.

I agree we're pretty far out from being able to live comfortably in space but I think to get there we kind of inevitably have to mine resources from space.

But what's the point of having large structures in space without people?

We can already get big stuff into space aka building sized, so you're taking about mega structures which seem rather pointless right now.
