Bitcoin will never die
Lol how can you sure about that bitcoin will never die? If people will stop using bitcoins or if price of bitcoins drops dramatically then there is a full chance that bitcoin will die and people will move to some other investments.
You're correct and that's why we need the help of the attorney, law enforcement agency, the government, the media and developers etc. If all the name mention put the effort to make bitcoin great there won't a situation for bitcoin to die.
And why do you think governments, law enforcement, the media want bitcoin to succeed and be great? Bitcoin is a threat to all of those parties, law enforcement see it as a way to move money without any control, the government see it as a way to lose their monopoly of the printing press and the media sees it as a way to lose revenue.
The main challenge is regulation and how the governments treat bitcoin and other cryptos. Will transactions be taxed somehow, casinos regulated, etc...
