Economies of scale like the dozens of radios that are within feet of my body right now. Economies of scale like smartphones so cheap that almost every single person over the age of 10 has one, including homeless people. Economies of scale like even if my main phone breaks, I can still power on and use the old one in my drawer from 2014, which is just as compatible with LTE as my new one.
Also, economy of scale like a single charging standard (USB) with plentiful cheap battery packs and solar panels; almost all having USB A available to plug into. The baofeng only charges through circular plug and dock; you can only charge if you have a battery pack or power source big enough to do mains-style AC power. Not all radios are like this, but it is extremely common. Best I found affordably is a raddiodity R2 (apparently illegal in USA, oops) walki talkie, which has docks that plug in via USB.
