Quirks are limited to a few people, and you can't do much without mass production. And my impression is that the MHA society deliberately discourages using quirks to their fullest extent if you're not already in an appropriate profession, analogously to real life Japanese society works. Ochako could make rocketry a thing, but society discourages quirk users from doing something so revolutionary and potentially harming stability.
Can't imagine teleport quirks being that good though, maybe if All for One was using them, but on their own, no way.
e: also, Ochako might not be able to handle doing that, even the simplest rockets would be far beyond her weight limit. Maybe endgame Ochako, but not current Ochako.
