The answer is right there in front of everyone. I’m surprised hardly anyone sees it when it has shown up in popular fiction before. In order to colonize space in our solar system we have to master living in space and building space habitats. If you live on a habitat full time then what do you care if it’s travelling around a star or towards another star or not even trying to go to a star and just moving from one interstellar object to another? If the habitat is big enough to contain two hundred million people then it is effectively the size of the world that most humans lived in for a large chunk of recorded history. The idea may seem strange to us but our current lives are very strange compared to the lives of those who lived when there were only two hundred million people alive on the planet.
