They always want to posture as if they'll be some critical service every emergency responder comes running to in a major disaster and it rarely if ever happens.
In the interests of not reinventing the wheel, you can see here in the same thread the comment from many other posters about the problems that they have with the behavior, attitude, and perspective of many ham radio operators.
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.
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.
Go look at the budget documents for the tower sites and entire radio communication networks that support public safety networks (police, fire, ambulance) on a scale of somewhere the size of King County, WA. Properly engineered hilltop tower sites with well maintained generators, redundant radio links, etc. Amateurs just don't have the resources to do these things properly and are a distraction at best.
My opinion is not new or novel - the people who built the att long lines microwave network in the pre fiber optic era very rarely if ever had anything to do with ham radio. Persons concerned with actual mission critical emergency communication systems learn the hard way that amateur dilettantes just don't have the financial resources or time to do it properly.
If you want to build an emergency communications network, it's going to cost money in real equipment and paying for the man hours of full time equivalent employees to build and run it.
