And that could happen after we have inspected every nook and cranny of our own solar system.
Oscillating between the null locations of the Lagrangian Points of the solar system, as they wind their clockwork way around, there is a natural path between the planets that has been called the Interplanetary Superhighway. It is the equivalent, by comparison to Hohmann Transfer Orbits, of a Hitchhiker's Guide to the Solar System.
We cam move cargo and colonies around, once we get into orbit somewhere. As Heinlein said, "Once you're in Earth orbit, you're halfway to anywhere."
Once we're well settled into the Solar System, we're halfway to the stars.
Humanity colonized all of Earth at a walking pace.

I’m just not sure getting the 1% to pay their fair share will fund colonization of the solar system.
