I think there is an entire angle to this issue that has been missed so far.
People like to watch NASCAR (God help them... it put's me to sleep), but you don't see them driving around at 300 MPH on the highway. Not even 110, which is pretty well within the reach of most modern vehicles. But what they do want is to play the "safe" kiddie version, the closed course formula 1 track for business execs, the go-cart track with no governors, that new track game for the PS3, etc.
You have some skate boarders who will do ridiculous stuff anywhere they can find a challenge (I can't relate to them either as I never cared for broken bones). Then you have the rest of them who are out there having a blast in the city skate park grinding on a certified and inspected rail and that little 6 inch ramp the city built in the middle of the park. When you go back to the early days of mass snowboarding as it took off int the 90s, I was out there trying it, and let me tell you it was a lot less painful than skate boarding... There is some guy who says he took up snowboarding because he missed skateboarding during winter. Well, the rest of us were just thrilled to get some snow up our coats instead of a bad case of road rash.
Just like Disney Land gives you a chance to pretend you are riding on a rocket ship to outer space (and deep down you trust that they would not endanger your life ... at least not without adequate insurance to compensate you for your loss), you have many hills that were struggling years ago now doing booming business because they've been able to manufacture "safe" trick parks, where you can pull a 360 without much to worry about (like trees and cliffs) and grind that nice wide rail that's about 10" off the soft snowy ground. These places would never be able to run a GS with the terrain they have, but they can blow snow on a few pieces of pipe and the ticket sales go up, up, up. My local hill with 200 ft. of vertical has one of those mega jumps like in the OP's picture. Only they set it up with an air bag so you don't need to land it to survive. I've even thought of giving it a try, then I remember that my chiropractor doesn't work on Sundays.
That's my take on the trick side of things at least. Back country extreme is a different animal. The closest thing I ever did to that was skiing Mt. Washington in the 90s. We hiked for what seemed like hours. My skis were constantly sliding around on my pack and jamming me in the thighs. Once we got there, we were saying out loud how "AWESOME!" it was. And there was the pure adrenaline rush from being somewhere that wasn't certified safe and insured over. But the actual skiing was actually like ... "meh". The bowl was like Disney Land full of people. The chutes were pretty short. Definitely nothing like what you saw people doing out west in the out-of-bounds videos of the day with nothing but trees and virgin powder. And even if there had been, there was no "GoPro" video to show off afterwards. I got my t-shirt and moved on.
Which gets to the point that I don't think marketing and hype beyond realistic expectation diminishes the sport. There will be many kids who are disappointed that they can't get the vertical or land the tricks that their TV counterparts are doing. But that disappointment won't necessarily turn them off to the sport, which, face it, for most novices is about showing off relative to the other people on the hill on a particular day. And if you can't land a better trick than that guy over there, you can always dump you money on cooler gear (no doubt why neon pink and green is making a come back folks!)
