Are you fucking kidding me? The meaning of government is LITERALLY "service to the people". They pay us with their service, we give them nothing. The only reason we'd ever need to give them money is for them to do a specific job for us. So say you want to lobby for a certain type of new weapon on the market so that you could ensure the politicians the new weapons are legal and safe (as in no intrinsic hazard to other people - an example of a hazard would be uranium shells which could kill everyone in the neighborhood just by sitting there and doing nothing except emit cancer causing radiation). You could pay the man to look at the bill first. But you'd just be part of a priority list and you can't ask them to get to yours first over the other bills on the priority list. A bill can take awhile to read and disrupts them from doing their other work, so i don't see why they couldn't ask YOU to pay them. Beyond that, government service is just a job. It's like keeping a homestead running. you just gotta do it... and in a taxless libertarian society you won't be required to work for the government (taxes) so you don't have to sell your crops if you don't want to. But your farm life is yours and yours alone, so your responsibility is to take care of it. Farming your own crops does not have intrinsic value other than putting food in your stomach. No one really owes you something for taking care of yourself.

In the normal sense of the word government it is a humble and fee-less service designed to HELP the people and to LISTEN to the people, as the PEOPLE are the boss, not the government. The government should have absolutely NOTHING to do with ANY currency, whether it's USD fiat, or Bitcoins.
