If there is an actual emergency, I would say these are a nifty introduction to ham radio.

Its amazing how far you can go with a somewhat simple setup.

Starting now means you'll end up being an important node later.

One big downside to ham radio (as someone with my license) is that you can’t use encryption. Which is fine for some use cases, but does limit the usefulness in the “government shut down the internet” kind of scenario.
Which, I suppose if you’re already using back-channels to circumvent some broader government censorship, maybe abiding by FCC rules isn’t a priority anymore, but IMO this is an area where large mesh networks of “consumer” devices with encryption very much still has value.

Yep i agree. Although it spunds like its trivial to break lora/tastic encryption from what was discussed online. Ill be honest i never went down that rabbit hole.

LoRa is already surfing on the bleeding edge of physics. There is no way to get anything more out of it, other than allocating wider EM spectrum for this usecase.
There are some radio amateurs in my area trying Meshcore on 169Mhz for example. There are also some new boards available that can do LoRa on 2.4Ghz, but both approaches have some downsides as well.
For a more stable and reliable network, we would also need radios capable of communicating on multiple channels simultaneously (remember, the whole thing started off as a reaction to really cheap, almost disposable dev boards), but now we’re approaching the complexity and requirements of the traditional mobile networks.
