So other users are broadcasting messages of third parties onwards? How many devices does it take to saturate the channel? What does this do for phone battery?

Yes, but messages can be encrypted so relaying parties can't read them. And yes, it would have an effect on battery and have very limited bandwidth compared to whatsapp (no sharing videos etc).
Like I said definitely not practical for messaging but I think something along these lines is how airtags work?
> definitely not practical for messaging
Text based messaging ala IRC? Just how quickly and how much do you type? A few hundred KiB exchanged between nodes only every 10 seconds or so ought to be able to accommodate thousands of simultaneous users in most scenarios. The impact on battery life should be far less than using a bluetooth headset.
Sorry I should be clearer: I think it actually might be feasible in a high population density area and if everyone uses it, but because of the limited range of bluetooth you really do need a high density of active nodes for it to work reliably.
A messaging system that often takes hours or days to get messages to the receiver is fairly useless and people will continue to prefer centralised systems, so there's a severe chicken-and-egg problem to solve there before anything like this can work
