The teleporter should be access-free

[Embolism]

The Space Prison no longer exists and there is a teleporter in the Space Diner. Anyone can use that.

So no the station teleporter doesn't need to be free access.

the space diner that coincidentally requires you to use a teleporter unless you want to waste a pod

Waste a pod? Eh. No one teleports to the Diner, everyone takes a pod there. It's like a 10 second journey.
