This is an interesting idea, is there any reason why the government owns the supply of money but they don't own a way to transfer it? Especially with electronic money, why isn't there a government payment processer? It kind of touches on the topic of taxes too, doesn't it? If the government owned a transaction system and you used that exclusively then they'll know everything you bought and sold. It's already an honour system so it's not like you're eliminating cash or even need to. Paranoid people could continue to use cash and the tax system would work exactly the same for those people. The government transaction system would be a convenience for most of the population. I'm spitballing here - my comment may not even make sense in context.
