Right, good major point, I understand that.

a) I have been using at least one popular paid relay. But it "sucks" if I have to keep paying over a lifetime to keep the notes there.

b) My main point is the power given to an entity upon creation of a secure private key used as nsec:

Such an entity, especially if additionally running a BTC node (which economically empowers Nostr protocol by orders of magnitude), should have the ability to FOREVER save notes timestamped to that private key, for example when saving to one's own local relay. The notes can/should be hash-timestamped onto the bitcoin blockchain as example.

I know that practically certain mentioned concepts are seperate but they can be interweaved. 

If I back up each Nostr note to my own local private relay, and each note is hash-timestamped on "a" blockchain, then my castle of notes should maintain its construction.

It should be possible to selectively see the presence of such notes in any relay that is built to accept them in the future, at any point. 

I don't want to be constantly talking and repeating myself online, even though that is what many algorithms value at the moment. That is the straling and manipulation of attention, perhaps one of the most valuable human assets.

I want to state things once and that's it. After that the algorithm will see that I have stated something in a note and that is all I need as a service.

Perhaps such relays need to be built. These would be the "decentralized empire organizations" of some sort, as they would contain the castles of the empire.

The notes should be undeleteable as long as they are bound to the nsec through hashes timestamped on a DLT (ie blockchain or hashgraph etc, ideally on bitcoin).

I have a need to know how to make this work so I'm ready for continued discussion.
