Playing a little bit of devil's advocate here . . .
It's an assertion that can't be proven or disproven. The only way to definitively know if someone is doping or not is if they piss hot. Then we know they doped. Besides that, we just can't know whether or not everybody's actually clean. And everything I've read online or heard in person (both currently as a weightlifter and formerly as a wrestler) indicates that the vast majority of internationally competitive athletes are on something. Everybody's looking for that edge because everybody wants to win.
Lots of national/regional level meets have qualifying standards and are thus not open to all competitors. And I fail to see how drugs in the sport would make these competitions pointless. Are you trying to say that if drug use was widespread and accepted there would no longer be a need to determine who the best lifter in a particular region/nation is?
I fail to see the logical connection between getting people interested in the sport at a young age (and getting them quality coaching), and whether or not drug use is widespread and/or more accepted. Maybe I'm missing something, but I think those two are largely separate issues (or should be, at least).
I don't think the acceptance of drug use as a necessary tool to be the best in the world has to kill the sport of weightlifting in North America. Unfortunately, as Glenn Pendlay said (thanks for finding that quote HT), PEDs are demonized viciously in North America. That mindset (which I think shows through to some extent in your opinions here) would have to change before drug use could be accepted at any level.
I'm trying to stay objective here and not put a moral spin on what I'm saying. To be honest I'm not sure which side of the fence I fall on. But I don't think the realization that one has to take drugs to be competitive at the highest echelons of the sport necessarily has to kill the sport at all levels. It's a choice that every serious athlete already makes at some point in their career. You have to decide how bad you want to be on that podium and what you're willing to risk to win. For better or for worse, it seems that in North America athletes are risking a lot more when they choose to break the rules and use PEDs than athletes in other parts of the world.
Gonna kill this post before I write a full essay here.
