Right? The only reason the new world was economically viable was because indigenous people molded the land to produce as much food as possible, and developed trail/road systems. It is very easy to create a self-sufficient colony in those conditions. This does not exist in space. Any project to live on another planet would require a government to take on huge expenses to build the infrastructure. Idk if anywhere else in the solar system could ever be viable for much other than robots doing resource extraction
