Aka: With current technology we couldn't make it even given infinite money and resources. Come back when graphene gets out of the lab.

Still pretty sci-fi, only maybe possible near term on a lower gravity body, like on the moon. But even that is still very far out from becoming economically and practically feasible instead of just technically possible.
