Even if we successfully build a space elevator and putting stuff on orbit becomes relatively free, we would still need to build a 100% sustainable spaceship. Or a completely game-changing technology like teleportation, and there's no proof such thing is practically possible.

No rules about nuclear power on ships, no worrying about contamination on other planets, laissez-faire attitude about risks that come with space launches/travel and fully automated control of rockets/spaceships, massive investment in life support systems and AI, etc.
