i don't think that government will do this because they should know about the technology first and make a study and research before they want to apply this. i think it will make an affect with crypto currency business but its not a big problem with other altcoins since the coins from the government is new and people still don't know what is the main benefit of that coins. if there is many of benefit from the coins, then people will be make use in trading like other altcoins.
Yes you are right, the government will not do this because country has it's own fees structure on banks, as bitcoin free structure is very low so government won't show much interest on other altcoins, now many countries are impressed with bitcoin technology so the government will plan to install this new technology for further access of buying and selling bitcoin, same as other commodities.
