I think you're overestimating how much bandwidth LoRa can handle. Because of airtime fairness, you're only allowed to be transmitting about 1% of the time. Best case LoRa is about 253 kb/s. 1% is 864 seconds, for a total of 25 megabytes a day. That would probably require you to be right next to the transmitter. Real world usages is going to be closer to single digit kilobits/second, maybe 1 megabyte/day. Also because of how Bitcoin is P2P, it's impossible to declare where the transaction is coming from. Transactions are all cryptographically signed and freely shared between nodes until picked up by miners. To figure out who the original sender is, you would need to host the majority of nodes so that the sender gives you the transaction first. Even then you can't prove they are the original sender rather than a rebroadcaster. There's a also few services that will broadcast a transaction for you: https://en.bitcoin.it/wiki/Transaction_broadcasting https://en.bitcoin.it/wiki/Transaction_broadcasting I don't disagree with you that Helium (or any crypto) is a scam. I couldn't dissuade one of my friends from buying the hotspots, and he has not made any money on them. There's also some sentiment that "Amazon should be paying me for the bandwidth they're using!" with Sidewalk. Also I don't think networks like Amazon Sidewalk or Helium get direct access to the internet: they wanna go through Amazon's API or Helium's to be able to charge the company fees for the broadcast. Probably to track and log it too since it's only a few bytes anyways.

Considering dial-up was typically ~48-56kbps, I would say I was underestimating how much bandwidth LoRa can handle ;) I guess the main issue with both Helium and Sidewalk is that anyone who hosts their own LoRa radio probably isn't using any IoT devices that would be outside Bluetooth or WiFi range at their home/business, so it's kind of a chicken-egg problem where presumably the people who would leverage a LoRa network are also NOT the people who would host a LoRa radio... hence the argument from people that they should be compensated by Amazon for hosting Sidewalk.
