Bitcoin transactions getting taxed or not becomes the point of debate there. Without tax many government services cannot be offered for free because the taxpayer's money is used to fund different government projects, development and services. Therefore fiat will be there even if bitcoin gets accepted or a system for paying taxes in bitcoin needs to be developed.

The common notion is that ruling class always imposes stuff on the lower strata. This is not always correct, the educated people need to make a proper analysis before making such a statement otherwise what is the use of logic?

Still some countries will be against having bitcoin getting accepted - this will effect them and put their country's technological development 10years back, which I hope does not happen.

Would also like to remind the OP about a plot twist : the rich people already own bitcoin, more than what this forum users can amass.
