With Bitcoin, all young people should stop listening to anyone over 40 years old (except for me).
Bitcoin solves many problems and it's future value depends on how many people wish to be participants in that solving.
For bank or government to compete in Bitcoin's problem solving capabilities (and therefore taking market share away from BTC) they would have to provide a non inflationary unit of exchange - with no barriers to entry for anyone in the world - with friction less near zero transfer costs - and complete freedom for users to have private or public status.
And then throw as many developers and engineers to keep their protocol ahead of the thousands of people around the world already developing BTC.
And then they have the impossible task of reproducing BTC's Network Effect - already 8 years ahead - and international in reach. All that from a single nation confinement.
