Nostr seems like a good solution.

there are many clients. encourage that diversity. try different options. engage with the devs about features and problems. fork your own that has improvements or simplifications.

there are many relays. post to multiple. use the bridges nostr:npub1q3sle0kvfsehgsuexttt3ugjd8xdklxfwwkh559wxckmzddywnws6cd26p built. run your own relay.

you will still have to work with people so they can find you. but that's just being a person.
