That's unique to american hams. 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.
Collecting replies like pokemon seems like a real waste of time in my opinion. I can send an ICMP ping to something I know is in Svalbard Norway across the regular Internet and get a reply, but I don't pin a postcard to a cork board on my wall celebrating my amazing technical accomplishment.

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.
