You need reusable rockets and space resources (Moon, asteroids) if you want to do space habitats at any reasonable scale.

To be clear, it wasn't my intention to trivialize the amazing accomplishment of reusable rockets, and your point is perfectly valid. I should have left it at me being excited for long term space habitats, and not even mentioned reusable rockets. As you've pointed out, of course reusable rockets will provide immense value to any space habitat. My unspoken position was that there are other ventures worth pursuing aside from the great leaps that leave us all in awe. The little things, like growing space lettuce, intelligent augmented reality to assist astronauts, etc.
