Yes. That's a good way of looking at it- Bitcoin's commitment was crystalized, and had essentially evolved. This line of thinking supports the idea that asking about a particular current controversy "what would Satoshi think" is irrelevant.
100%. It's also interesting to think of the power of Satoshi (or really, any prominent figure) in terms of coelescing these kinds of commitments; and how that changes with time, and the nature of the enterprise.
I expect that if Satoshi had returned six years ago (or whatever) like Gandalf the White, his opinion on the blocksize war would have had great impact. I suspect that if he returned, now, with a hot take on Ordinals, that it wouldn't matter much.
