Most hunters don't spend thousands of dollars travelling to other states or provinces. The RS crowd is not representative of the average hunter. I didn't say that hunters are only interested in the meat, but that is generally the primary motivator for most hunters I've interacted with.
The reasons for low success rates vary, and I was speaking specifically about certain tags I hunt that have a low success rate mainly because of an extremely low density of legal target animals. As I said, even the most skilled an dedicated hunters rarely fill those tags. As you've mentioned, OTC archery elk in some states is on the opposite end of the spectrum - plenty of legal animals, but the skill required to get a shot is very high. Low success rates are not as demotivating because, in that case, experience and skill bring an increase in individual success. A guy can make his own luck. The notion that 5% of guys do 90% of the killing is also because of specialized land access that most people can't get. I've seen it. That's extremely demotivating for the vast majority that can't get such access. It's also true that 90% of statistics are made up 95% of the time.
As I mentioned, I think a balance between opportunity and success is ideal. One method is to use a hybrid draw/OTC system in each unit. OTC tags available with certain restrictions (regardless of whether those are based on the animal or the tech) that set a fairly high standard with low success rates, combined with a few draw tags with much less restrictions and higher success rates. That way, a guy could hunt every year on the OTC opportunity, but every few years maybe draw and fill a tag.
FYI, I have spent my life and hunting career just north of Montana, which I would call the "West." While I am not in favour of limiting tech beyond the current system of having separate prime seasons for lower tech (archery, ML, general, etc.), at this point in time I would be okay with eliminating out-of-state/province hunting altogether.
