I think it falls under the 1st world problems syndrome. Reloading is a means to an end or an addiction or both. If reloading doesn't check a box for someone then there is simply no reason for someone to make the time and space investment. I don't tie my own flies although I have tied thousands in the past.
I have friends that hunt and I have offered to loan my old equipment or use of my reloading room. They just buy a couple of boxes of bullets instead just like I stop by the fly shop and grab a dozen flies. I also don't build my own arrows for archery hunting. Folks have the opportunity to do many other things with their time and reloading just isn't at the top of the list.
When I started reloading I had more time than money. My girlfriend bought me a complete RCBS kit for $199 for Christmas. Because of funds at the time, I didn't have a multitude of competing things I could be doing. I didn't have atv, sxs, boat, raft, cabin, house, rentals, motorcycles, cars, trucks, kids, elderly parents, a business and a regular job. I don't think I would be doing it today if I hadn't learned to reload when I had fewer distractions and fewer opportunities.
Today it has clearly progressed to an all out addiction.
Opportunities just seem to be greater these days for the younger generation. I am not entirely sure I can fault them for picking another opportunity over reloading. I can kind of see the end of the world argument, but I am not sure reloading is the first skill people are missing in that scenario.
Another aspect is teaching basics and letting someone progress through the process naturally. I have been at it for 30+ years and it is hard to just show someone the basics they need to know to get started. If you show them too much it just seems daunting and ridiculously expensive. Most of the things we dwell on just aren't relevant to someone getting started. They don't need $300 neck sizing dies with a micrometer seater, they don't need to figure out neck tension, they don't need to worry about shoulder set back, they don't need to anneal, they don't need to worry about seating depth, they don't need a $600 scale or a supertrickler. We sometimes make it look like rebuilding an aircraft jet engine and certifying it for flight. And then to justify our anal addiction we make it sound super dangerous.
In reality it is pretty **** simple and safe if you just know the basics and respect the reloading manual loads. When someone wants to see how to reload I dig out my $199 setup ($600 in today's dollars) and I show them the basics. If that is too much then there isn't any reason to go any further.
