Human-rated just means that it can carry humans. I didn't say human-rated according to NASA's requirements. The only requirements for 'human rating' are NASA's requirements for carrying NASA astronauts. There are no other bodies 'rating' certifying' or in any other way approving any particular space vehicle for carrying passengers.True, but SpaceX's early goals for crewed Starship will surely include service to LEO stations and will be a part of the solution for retiring Crew Dragon. This means carrying NASA astronauts, which will require NASA certification. They won't want to be forced to redesign to achieve this certification. The economic driver for this is that they cannot retire F9 until they can retire Crew Dragon, and fixed costs cause F9 to become unprofitable once its flight rate is reduced to only Crew Dragon. I suppose SpaceX could decline to bid on further CCP follow-ons, but that would risk antagonizing NASA. Once Cargo Starship is operational, I think the F9 flight rate will drop quickly, leaving only CRS and CCP. This will happen slower than SpaceX amazing people believe but faster than most observers seem to think.Sounds to me as if there's a bunch of confusion here . People seem to be conflating technically capable of carrying live humans from orbit-to-orbit, technically capable of carrying live humans from Earth's surface to orbit and back, technically capable of carrying live humans from lunar orbit to surface and back and meeting someone's standards and doing the paperwork to prove some or all of these capabilities and calling it all human-rating.Some of the posts, such as yg1968's, make a lot more sense if all that's being talked about is the technology, like ECLSS, toilets, radiation protection, etc. rather than any rating or certification.

I believe that SpaceX needs NASA as an anchor tenant for its crewed Starship to make sense from a business perspective. Uncrewed Starship is different as it has a business case on its own.

Uncrewed Starship is different as it has a business case on its own.SpaceX might get crazy again. They needed an anchor tenant for Falcon 9, so they created Starlink. They may be able to do the equivalent for Crewed Starship with space tourism, including flights of various lengths to LEO with crew remaining inboard, or by launching one or more Starships to serve as CLDs for tourism, commerce, and research.But this is the Artemis political thread, so how is this relevant?! Well, if SpaceX creates a viable crewed Starship that routinely put people in LEO, then there are all sorts of possible cost-effective Artemis mission profiles that do not include SLS/Orion.

Well, if SpaceX creates a viable crewed Starship that routinely put people in LEO, then there are all sorts of possible cost-effective Artemis mission profiles that do not include SLS/Orion.I agree that there is a market for private astronaut missions in LEO, the Moon and Mars but I don't know if that market is large enough to justify the billions that are necessary for the development of crewed Starship. I am thankful for the Dear Moon and Polaris 3 missions but I don't think that they are sufficient to fund the development of a crewed Starship. When HLS Starship won a $3B contract under Option A, I was happy about it because Starship probably needs about $10B for its development which is a lot of money. Having NASA pay for part of that helps a lot. I am guessing that Option B (for the development of the sustainable HLS Starship) will provide SpaceX another $1B or so. From an investment and business perspective, it is important for SpaceX to win some of these contracts.
Option B is only one demo mission but it also includes funding for the development of the sustainable lander. For missions after that, there will be something called the HLS Sustaining lunar transport services procurement which should start around 2027 or 2028.
Because of that, I care less about SLS/etc than I used to. we’re living in one of the most optimal timelines, potentially better for human spaceflight than the dreamers of 10, 25 years ago.
We live in one of the best timelines.
A good case could be made that... NASA was once stuck with the ISS - never mind, they used it (through COTS and CCDEV) to pump money and HSF knowledge into SpaceX.
NASA was once stuck with SLS-Orion for Artemis - never mind, they used it (through HLS) to pump money and HSF knowledge into SpaceX.
I have this sneaking suspicion that, when they picked SpaceX as the HLS winner, NASA had a long term plan. They rammed Starship-SLS into Artemis with an eye on ditching SLS-Orion in the future. You never know, if Congress ever see the light... - short term, anchoring Artemis to Starship makes it harder to cancel - long term: just ditch SLS-Orion-Gateway and go full Starship to the Moon.
My gut feeling is that the following will happen within the next decade, to 2032
One of the primary reasons for the Space Transportation System (i.e. Shuttle) was to BUILD a space station in LEO, so the ISS was really the culmination of the Shuttle program.

Space stations were no more than a gleam in NASA collective eye at the time. Only a decade and a half later, after the Challenger accident made obvious the Shuttle's abject failure to fulfil its intended role, was a space station project initiated.
