Posture, no one can compete, not even NASA.

Yeah who is going to deliver faster and more reliable than SpaceX? Boeing? LM?

Doubt

I don't know who else can, but I do seriously doubt SpaceX is going to be able to deliver within the next decade or so either.

They have a pretty good chance, actually. They are almost done with the hard parts of the Starship.

That's what Musk wants you to believe.

In reality, reusability was the Achilles heel of the space shuttle, due to the thermal insulator tiles that could be easily damaged during reentry, so they had to be rechecked rigorously before the next flight, and the damaged tiles replaced. We haven't seen any of that - so far only the booster was reused, somewhat, as in 2 were reused, with one failure and one success, but only much later.

And then there is the orbital refueling, but that is so far in the future that it's not even worth discussing.

Not just due to the tiles!

They had to take a lot of the back end of the shuttle apart after every landing, which was cumbersome because things weren't packed right for that. Also, they used hydrazine for the (many!) smaller rocket engines and that requires special protective suits and breathing equipment.

Starship doesn't use hydrazine and the big engines are pretty fast to remove/mount. We've seen them do that many times now.

Shuttle tiles were tested by having somebody going around and pinging them all with a special mallet and using a cart with a special computer that checked if they made the right sound.

Starship tiles can be inspected remotely and quickly with a camera.

Replacing a shuttle tile wasn't easy. Replacing a Starship tile is fairly easy. They have done it many, many times already. The question isn't whether they can do it fast (they can) or easily (they can) or whether they can detect bad tiles (they can). It's not even whether they can tolerate a few missing or defective tiles (they can). The only question there is whether enough fail so that the replacement time cuts too much into the recycling time budget for when they want to launch Starships really fast. We don't know that yet. They won't be needing really fast turnarounds for some time so there's plenty of opportunity to fix any issues with tile design/placement and with the underlying thermal blankets.

Don't argue by analogies. Especially not bad ones.
