Depends on your definition of you .

If it means life , then We don’t need humans to make life interplanetary at all; that is least efficient way to go about it ; we should instead design/choose lifeforms that are most likely to survive the target environment not depend on brittle/expensive life support technology to spread life through the system.

If the you is intelligence , then spreading AI could be a better approach rather than humans who are unlikely to be able evolve to survive in a hostile environment naturally anytime soon.

Humans in our current form in space is always going to expensive tourism no matter how much science fiction likes to pretend otherwise .
