The joke's on you; multiple startups are working on satellites that can communicate with unmodified cell phones. It will probably be limited to SMS but it's not literally impossible.
Plenty of startups works on impractical stuff. Not to pass judgement but the fact that startups are trying doesn't necessarily confirm validity. See wireless power.
You can buy a range of actual wireless power tech today going all the way back to crystal radio‘s. Charging pads, RFID tags, and fully radio powered sensors etc aren’t want we thing of as wireless power but yesterday’s magic is today’s background noise.
Yesterday's magic is today's Ikea product. I have a few of their 5 Euro Livboj Qi charging pads for charging my phone and Airpods and they work just fine.
