Agree with the above.
The Link provided by ORAC does mention some of the potential pitfalls in trying to use Starship in the near to medium term - no proven record at all when it comes to rendezvous, support of EVAs, and ATM no manipulator arm.
The Shuttle program ending (for good reason) meant an almost total loss of the ability to perform satellite capture and/or perform on-orbit repairs and it’s going to take some time to get that capability back.
Maybe if Hubble is still in orbit and still stable/controllable when Starship and all else that is needed has matured there will be a rethink.
