They don't have to discuss the benefits to label Bitcoiners as tax dodgers, scammers, greater fools, parasites of various stripes. That will give them cover in a crisis to bring in punitive laws that target the UX of self-custody and herd people custodial solutions where they can be 6102'd.

I doubt it. If the establishment tries to talk about bitcoin, it will attract a lot of attention and nocoiners will get more curious to understand. Once they understand, they will try to get in. From the establishment viewpoint, they will try to silence any mention of it, not blast the word from a megaphone. Attempts of bad publicity will backfire. 

So the question is whether more commoners will discover it on their own when shit hits the fan.

That's ok. "Bitcoiners" is kinda gross anyway with all the fiat maxis in that group.

I think Bitcoiners will be vilified and scapegoated, which will put downward pressure on price for a while.
