Almost entirely.

Your identity (npub/nsec) follows you from client to client, app to app. If one client bans you (which is highly unlikely in the first place considering the ethos here), you can simply jump to another and your entire history, posts, followers etc come with you there as if nothing happened.

If similar problems happen to relays (bans or govt takedown etc) then you simply add a different relay (or just use multiple relays to begin with) and you're back on the network as if nothing had happened.

You wield in your hands the power of decentralized systems.
