I've seen plenty of advertisements for government services.
> no duplication of effort (and greater scale)
The "duplication of effort" is a plus for a functioning market bringing competition, cooperation, lower cost, and increased standard of living. [1]
> no sales department
Whether they have this or that department will be greatly outweighed by the massive bureaucratic burden and special interest groups.
> no executive bonuses at all levels
If they are to have competent people to run the program (which is probably asking too much of a government program) then they will have to be compensated similarly as they would be in a private organization, whether that includes bonuses or not.
> no legal department
Will be replaced by the armed enforcement department.
> no billing
There is but it is outsourced to the IRS or other department
> no metering
Like it or not, access to the internet is a scarce resource, and regardless of who operates the infrastructure there are technical bottlenecks which have to be managed. If there are no caps, no metering it will be guaranteed to be overrun by abusers and be an overall horrible experience. This will essentially turn internet access into tragedy of the commons.
