Reseach on potentially dangerous materials has been going on for generations; why would the outcomes be worse now?

Your average 22yo isn't doing something like this with his buddies. Between the equipment, expertise, consumables, etc, etc, it's clearly the kind of thing that's organized and financially backed by someone (i.e. like most small business). So while most may lose money, we don't know if it's a "send out three teams and one winner pays for two losers" type situation.

The way I see it these mammoth bits are far more likely to be preserved if used as home decor or whatever somewhere in China than if they wind up rotting away when (let's be real here, probably not an "if") the permafrost melts or in some mine's tailings pile when some other industry comes through. If this was all above the table there'd be more ancillary industry around it too. Sure the tusk might be cost prohibitive but why can't every highschool biology department have a "worthless" femur or jaw or backbone segment? Oh, because it's illegal so "less profitable stuff" (i.e. same reason the cartel doesn't move low density product) like that gets discarded, that's why.
