With regards to secure technology ,governments, or at least armies and intelligence agencies are most likely leading the race. With regards embezzeling government money in such system: i believe(and could be wrong), that generally, this isn't a worse problem than the private system. And again, this a problem armies/intel agencies have been dealing it over a long time ,with far higher risks. And of course there's always options of secure auditing(maybe like bitcoin) , further reducing the risk. With regards to key distribution - if we look at the awful security afforded by credit cards, even though we know how to solve this(chip and pin, for ex.) i'm not sure the government is worse. As for the issues of power of government and potential for abuse of that power - sure i definitely agree with you(it's a huge problem even today). But again, my comment was about that it's possible to do so in a way that would be compatible with online commerce.
