PV only takes you so far. It'll power your television set but that shit won't get you into space. And it certainly doesn't make a good building material. I'm not just talking about electricity generation here. There's so much more that civilization runs on, and the Belt's full of it.
And how on Earth could we
not be restricted by the drainage of Earth's natural resources? Think about it for a second. In the scenario I've presented, we've pretty much pillaged the Earth because when we were doing it, we had the Belt/Jupiter/everything else to leverage and we really don't think that far ahead (we weren't even going two centuries ahead when we all switched to petrol, and for most people 50 years from now is some imponderably long time where we'll somehow end up having beautiful green women and flying across space in the USS
Enterprise with Mr. Spock aboard when in the last 50 years the major accomplishment has been the development of a way to cheaply deliver porn to the privacy of lonely people's homes).
So there's not much left on Earth that we could use, if, say, some sort of horrible collapse might happen, like what you might experience once the Solar System's exploitable resources have been used up. So whoever's stuck here on Earth would need to build up again from what they had at hand. You don't think space-ships just come out of nowhere, do you? And if there's nothing at hand... then it follows that they can't build up.
And you can't just assume some mad scientist will invent a faster-than-light engine before we hit that point, because right now physicists are pretty damn sure it's not even possible.
At that comment, I'm certain someone who believes in the infinite power of science to make the impossible possible will point out other things we used to think were impossible - like spaceflight in the first place - were in fact possible. I'll just say that there are also tons of things that we thought were impossible, and were in fact just not possible, like perpetual motion. It's not a safe assumption that just because we believe it to be impossible today means that someday we'll work around it, because some shit just ain't possible.
