2 to 3 years is wildly optimistic. Of the 5 launches last year 3 were failures and it's not even close to be ready for humans yet.

Some people don’t understand the difference between testing and use. You can afford to test when your launches cost 1/100 of SLS launches instead of risking human lives. Artemis II was human rated with zero launches of its life support equipment, modeling failures of its heat shield, multiple power issues in its only predecessor flight in space. Starship will carry humans after hundreds of launches and landings.

		I don't believe that to be true. Starship may host humans next year if it can get to a stable orbit and manage to demonstrate sufficient control for docking. It is extremely unlikely to demonstrate any environmental control before that.
