I think we agree on this. there's decentralization in theory or by design and then there's decentralization in practice.

bitcoin is no different here. the vast majority of all holders are using custodial services like coinbase, and in some circumstances, that's no better than having your money in a bank.

and yet, I'd argue that bitcoin makes the point and shows the path, even if most will never walk it. the option is there, and those that wish to, can use it. but I also believe that more and more people will take that path over time, and if we're not out there clearing it, they definitely won't. nostr may have no real impact on the bulk of people who use social networks and communications.

but as you say, we're here for that. so whether the crowd jumps on right away or not, nostr still breaks the network effect for those who use it. just like bitcoin doesn't break seigniorage for those who don't hold it.
