I’d say it depends. If Nostr depends on big relays that cost thousands of dollars to operate perhaps not.
But if it’s truly decentralized and there are thousands and thousands of relays all holding the network then it might hold just like Bitcoin nodes. This scenario is the best scenario but also one we will need to wait for it to play out.
For all the strides made to make running relays as easy as possible it still requires medium technical knowledge to run one successfully.
