Cashu tokens have been

1) send to space and back to earth, and

2) sent over mesh network radio

3) sent offline from phone to phone

Are we in a cypherpunk's dream?

Can we really consider them “sent” if they’ve yet to be redeemed? The double spend is the real risk isn’t it?

There are various ways to prevent double-spending in a partially-offline scenario. If one of the parties is offline but the other one is online, you can prevent double-spends. If nobody is online, the token can be double-spent until the receiver comes back online.
