>It isn't suited for real-time chat (nevermind secure)
It is encrypted on private channels and direct messages.

I don't know from where your information's are from, but for sure not from reality. Voice encryption/scramble on Amateur-Band's is not allowed, everything else is ok.
I know what features it claims to have. The question is how well this can work on bands (US915, EU868) that very strictly limit the amount of time a device may transmit. IMHO you can't really have interactive chat on a mesh network over lora in those bands.
>I know what features it claims to have.
Yeah...no i don't think so.

Devices allow 10% Airtime on ISM here (EU) that's about 300 messages (with 255 characters) per hour, and yes interactive chat is possible with around 20 seconds of lag.
EDIT: I stop here, so much half knowledge that sounds educated but is in fact just wrong and TBH not even sure if i talk to a selfhosted AI.
Have a good Day.
Yes, in the EU one subband allows 10%, the rest is 1%. I believe that Meshtastic uses the whole 250kHz of that subband by default. This is by far the most relaxed constraints of what is available in the EU and US. That's about 180 max. size messages per hour (at longfast) per device but you need to take into account retransmissions, acks, mesh management and routing of third party messages. So it may work, barely, for this specific config and very small number of people or 1-to-1, but that's it.
I am not picking on Meshtastic specifically, it's just that Lora and, especially the regs on those bands are such that some applications are never going to work well beyond extremely small meshes, if at all.
