Then again, one could suppose that it's all really the fault of those who allow themselves to remain in the sport with any aspirations outside of market forces. The sport was built by lumberjacks and floats on the success of developers. All of the soul and individuality claimed in snowsports' styles are really perfectly placed product promotions at an underutilized target markets of indy-fag-hipsters from Seattle, and yuppies from the Bay. So just remember, when you finally get to buy that sled so that bad park days can be turned to fruitful backcountry expeditions, you're gallantly doing your part to keep the American dream of prosperity alive, because infinite growth is the heavenly mandate of the land. But do us a favor and remember not to teach your kids too much about what powder used to be and remember that we're all digging our own graves.
You spelled yuppies wrong.
Just thought I'd tell you.
But really, you're quite spot-on with your comments... I have only one thing to say.  We don't like skiing because it is built around self-destruction.  We like self destruction because skiing is built around it.
Skiing gets to be more important than suicide.  Sure, Kurt Cobain was cool.  But was it because of his suicide?  or was it because of his music?
You could argue both ways.  For example, was Lincoln really that great a president?  He did, after all, directly defy the Constitution by denying the writ of Habeas Corpus to enemies of the Union and hosting militarily "supervised" voting sessions in the border states, among other things.
But he was murdered, shortly after his side won the war.  So we like him, because he died after being a part of something cool.  Regardless whether it is suicide or not (in Lincoln's case it wasn't) we empathize and grow to like things that are terminated after doing something cool.
Did people like Lincoln in the short week between the end of the Civil War and his assassination?  Yes.  Did they like him and miss him even more once his death set in?  Of course.
The same goes for skiing.  We like skiing now, because it is truly the best sport in the world.  Would I continue skiing without lifts, snow cats, and sleds?  Yes, of course.  Snow cats piss me off, because they ruin good mogul runs, and often enough, powder days.  Does park skiing depend on them?  Yeah, big kickers do, but jibbery and rails will always be better hand made.  Not to mention that hauling a cat into the backcountry would ruin the powder landings we love Nimbus for so much.
How about sleds?  This one's a bit harder, because we know how hard it would be to have two-day trips into the backcountry without them.  It'd take far longer to accomplish the same thing.  But would skiing survive without them?  Sure thing.  There are plenty of people who use their AT gear--bindings, skins, and the like--to get out there and ski.
Most difficult to give up are the lifts.  Skiing's popularity among the masses would surely fall.  But would a few die-hards still be out there doing it?  Yeah.  And would the number of these die-hards be far larger than it would have been without the invention of lifts in the first place?  Yes, it would.
I know that without lifts, I would likely have never begun skiing.  But if they were taken away from me right now, the first thing I'd do is get out and buy some Marker Dukes and climbing skins, and a bigger backpack + some avy gear.  And I'd get out there and enjoy the unpopulated slopes of Squaw, and the empty terrain on Mt. Hood.  Do people come to Hood in the summer because of the lifts?  Yeah, but would they come if it weren't for them?  I'd imagine that some still would.  After all, the other, undeveloped volcanoes of Norcal, Oregon, and Washington still get skier traffic in the summers, just far less than the developed ones.
Though skiing does pull the proverbial gun closer and closer to its foot, it only pulls to the foot.  And we know that a person with a bullet hole in their foot can still do pull-ups, write, and wildly flail their arms about, right?  So skiing will likely one day suffer from a huge drop in popularity, and many of the smaller ski companies will probably go bankrupt, but the mountaneering spirit that drives a minority of skiers would never die.  Just because something's crippled doesn't mean people wouldn't care about it-- look at Christopher Reeves.  Everyone loved him as superman, and though he couldn't really do any of the mundane things we take for granted--walking, running, even crossing his legs--after his accident, he still had a wide following among his former fans.
The only thing we really have to worry about is the melting of the snow that appears to be happening, and that Al Gore insists is true.  And while I know and believe that everything we as humans do hurts our environment and helps destroy the world, I also know that skiing will live on, forever, even if only on snowflex and on indoor slopes with small amounts of vert.  But the way things are progressing in the technological world, who knows.  Maybe when it truly becomes too warm for snow to ever fall, someone will put a roof over little cottonwood canyon, and block off the heat, and turn on the snow guns.  I'm not saying I want that to happen, nor am I saying it will, but nothing is out of the picture.
Skiers are far too stubborn to die out.
