Yes. And with Mars, on a smaller scale, there is just about the same problem: Of course it is interesting and fascinating to explore it. Or go there once for the funsies. Much harder to establish something that brings back more value than it took to bring it there. Even just keeping Humans alive there will probably be a very expensive proposition for at least a century or more, before there is a solution to the apparent economic futility of colonizing Mars. Bringing back stuff from another star? Forget it. The only reason to go there is to be there. Or even more precisely, you send your children/creations there for their children/creations to be there.
