Ecash is the only way to transfer Bitcoin value, with no record of the transfer taking place. You can't transfer Bitcoin on-chain if you can't connect to the network to broadcast your transactions to miners. You can't transfer Bitcoin via lightning unless your node can connect to my node either directly or routing via other nodes. You can transfer ecash to me via nostr, email, homing pigeon, Morse code, and I think someone has even done it using sound over a meshtastic network.
