In Portal, using the portal gun to get to the moon is the obvious space travel usage, but I think people are overlooking how it’d let you trivially break the rocket equation.
Hell, you could build a >1g torchship using nothing but the ocean.

@foone@digipres.club The Pierson’s Puppeteers did this to fuel probes in Ringworld. The only difference was their technology required a physical teleportation device to be placed at the destination instead of just opening a portal anywhere, & transmission was limited to the speed of light.
