Most of the world just collects dx entities like pokemon, pota/sota locations, backpain complaints on nets and argue if ft8 counts or not for anything.
Similarly, for all the effort that people put forth to do EME and get bidirectional traffic with some tiny data payload bounced off the moon, they could be engineering real world production systems that do something cool with real, existing LEO, MEO, geostationary two way satellite data systems, accomplishing some useful purpose. Or at least doing something like cubesat ham radio traffic relays to carry a useful payload.
A great deal of what analog ham radio enthusiasts seem to care about falls into the category of being a dilettante in my opinion and has very little bearing on building serious networks that carry traffic/payloads people will rely upon .
There are many different niches in the amateur radio hobby. Some people want to buy off the shelf radios and antennas to make contacts over the air. Some people want to experiment with their homebrew designs and see how far their signal reaches. Some people want to experiment with very low power radios. Some people (including a Nobel prize winner!) want to experiment with new digital communication protocols for amateur radio use. And yes, some people want to use amateur radio for emergency communication purposes.
Why is it so wasteful for any of these groups to do what they're doing instead of applying their skills to something "useful"? Why is it any more wasteful than participants in other hobbies? That also ignores the fact that many amateur radio operators _do_ apply themselves to "useful" things: they're electrical engineers, physicists, software engineers, educators, military or emergency personnel, etc.
It's a hobby. "Let people enjoy things". Please remember this: it's a hobby. It's right there in the name: amateur radio. We're not trying to be world-class industry-leading RF engineers.
No, not everything in the world has to be utilitarian or accomplish a purpose. But amateur radio is continually living in the past, their entire communication paradigm is often based on something akin to circuit-switched networking when the packet based networking world passed them by quite some years ago.
But hey, like with everest, you don't have to do EME or collect countries if you don't want, nor you have to climb different mountain tops, hike the trails, etc. You don't even need to travel, it's cheaper just to see everything on youtube.
Some people like their hobbies, and if that hobby is to climb high mountains or reach as many countries as possible, then why not? Amateur radio is a hobby, if you want to work on eg. starlink, they could ne hiring.
