I'd be very surprised if bitcoin failed, but if it did fail, it will not be for the op's reasons. It will solely be due to strong opposition from the international bankers and the 1% of the population who holds 99% of the money. They could easily pay off governments to ban bitcoin, or they could put millions of dollars into ads that brainwash the sheeple into staying away from bitcoin.
This would be the most logical possibility.
It is very difficult if not impossible to control what other people think (although social media can come very close to doing just that).
The "1%" do not need or want the status quo to stay the same as far as how money is used and measured. The very rich can easily adapt (more so then most everyone else) and is willing to take risks (on things like bitcoin)
