Capitalism requires infinite growth, you would never see sparsely populated worlds because any time a world lacked population the capitalists would simply import more, use clones, or use robots to make up for it.

This is why feudalism is so important to space settings. Stuff like Ringworlds and Dyson Spheres and all that weird giant shit which is difficult to comprehend is the domain of a system that never stops growing no matter what the costs. Feudalism is much more content with stability and stagnation
