Even us users do really saw the potential of bitcoin regarding on its benefits and convenience but government wouldnt still convince them to use or adopt it because they know already that they cant able to control it therefore they would surely create their own replica into bitcoin and im assure it would spread fast because its being regulated and people who dont know bitcoin will directly believe into it.
I agree that when a government create their own replica of Bitcoin, it will be absorbed by people because of this reason. They have the authority. The created replica will automatically have valuation depend on how the government decides its value making merchant more comfortable in using them than the high volatility Bitcoin. Aside from that, either the masses like it or not, it is an implementation, there is no way for us to reject it unless we go out in the street but i think that will be futile. This replica if approved by group of commerce will then be used by companies and then may apply it to their payment system for their employees.
A cashless society will in fact promote bitcoins as more and more people will start using digital payments or bitcoins. We all know bitcoins is the father of online transactions just we need to get it accepted at big stores and sites.
Seem you mixed up your details.
As far as I know online transaction was made possible way back 1979 when Michael Aldrich invented online shopping. I don't know if Bitcoin exist way back that time.
