You said it yourself: the internet remained decentralized and became even more decentralized, and it happened in parallel to the advent of centralized services. That's causality, not coincidence. Competence among services ensures the internet will remain decentralized, for no player wants to be at the mercy of the other, and the same will happen to bitcoin. Decentralization will remain in the hands of people via entrepreneurship and competence among services. That's the fundamental division of work mechanism that will allow bitcoin to become people's money. Do not neglect decentralization of services out of the equation. Do take the internet as an example of that. We see yet another immediate example of exactly that with Nostr and the development of its clients, who for the sake of their business implemented more and better relays.
