Spinhabs are ultimately going to be necessary beyond a certain level of population because there's only so much land to go around in the solar system. Pic related. Spinhabs turn solid volume into habitable surface area and can be assembled from otherwise useless low-gravity rocks.

I live on Fyn, it is a 3000km^2 island. It may not seem like much to some but last year I have been exploring it lots and lots on my bike and I doubt I have even seen 10% of it. One day I will finally finish exploring it, and maybe then I can ride a spaceship to the planet Stephano that orbits Uranus, which is estimated to have the surface area of another Fyn; adventure begins annew! After that I might will feel I have seen it all, but if I keep going to the edge of the solar system I could bump into the planet FarFarOut, which is a mad 167 fyns more, exploration for the rest of my days! And yet both those places are too "small" to even be mentioned individually in this fun map. Not that I really need to go there, when Earth is 51000 fyns, and that's not even including all the sea.

Someone made a beautiful video showing off the island, I don't think it gets anywhere near showing 10% of the place either:

When I reached Kerteminde I thought of it as "The town at the end of the world", but really there is so much more of it.

I was curios how much land there was in solar system, and I found this picture. Though I don't think it counts stuff like the potential inner rock core of gas giants which I guess you could stand on if you can get through all the gas.

even if you spend thousands of years terraforming and shifting orbits to make the surface of all rocky planets and asteroids habitable you end up with a meagre result
