It is true anybody (or bot) can spin up new identites so the count of pubkeys doesn't say much.

It is also true that there is spam. But it is avoidable. Spam lives in the general feed and in replies. You can configure clients to ignore the general feed, only show posts of people you follow (and maybe of people they follow). If you want to meet new people, then use relays that filter spam. You have choices of how to solve this; nostr is about putting the decisions in your hands.

I have not seen any client that creates a new ID. I've always imported my key and used my same ID from day one.

But you are 100% that the community is heavily slanted towards bitcoin enthusiasts.

And tada! You have centralization... Because filtering spam is a very complex operation.
