Why is it "getting old"? It's a fair concern that something so volatile should be examined critically and relentlessly. People don't just "get a stiff drink and accept they'll lose money" if it goes down---they jump out of windows.
I'm hesitant to jump in cryptocurrency discussions because 1) I know too little about them, even at a technical level and 2) they're consistently filled with "emotional hyperbole" (that we agree on) from both ends.
I think governments/regulators should have some say the same way you'd want them to regulate any financial instrument and punish Ponzi schemers and pump-and-dumpers.
I'd like to think about the motives of both sides from being so passionate. For naysayers, I imagine it's a bit of sour grapes. For yaysayers, it's a bit more obvious---once the hype dies, they'll stop making money.
