The main problem is that you kicked down the door with guns drawn and demanded a discussion while claiming the real reason is what you've stated. If you are looking for discussion, you've left little room for a debate.
If you want differing views, I'll bite.
My opinion is that it simply isn't a priority anymore. For example, why hunt when you can buy steaks any time you want? I compare it to a gym membership. In that you can have everything you need to work out but it is intrinsic. Once it's a priority, you will go to the gym. Similarly to hunting, even without a mentor you can read and learn. It boils down to a personal commitment. Frankly, that's too hard for some people just like working out is too hard.
But I don't think you came on here for a healthy debate. You're instigating and responding defensively.
A small piece of advice, learn to adapt to your environment. Don't demand for people, that have an enormous amount of experience, to listen to you. I have very little experience myself so I'm not included in that group.
Instead of picking a fight with this forum, go be a part of the solution.
