The actual physical reality is that our solar system alone, if developed with the materials that exist in the form of asteroids and eventually planets, has more living space than every habitable planet in our galaxy, combined.
The difference between living in artificial habitats and living on plants is like the difference between living in a house and living in a cave. A single mountain may have a couple of caves the cavemen can fight over, while a more advanced society just quarries the rock and can from a single mountain get enough of it to cover a continent in houses.
The energy and material abundance that exist within our solar system is enormous, we will never want for any physical resource or energy. This is based purely on using solar energy from our Sun, there is no need to fusion until you want to colonize our Oort cloud.
