Seems pointless to keep persisting with it given the ISS is approaching EOL. There are also a finite supply of boosters left it can fly on.
Wasn't it also supposed to go to the moon station for Artemis? Or is that also a non-starter if Starship works out?
Nope, Starliner is not designed to go beyond low Earth orbit. You might be thinking of the commercial space stations intended to replace the ISS, where, yes, Starliner was proposed as the crew transport for Blue Origin's station.
