That sounds logistically very difficult. The government would need to decide _which_ standards are worth paying for. You certainly couldn't have everyone who wants to just bill the government for however much they decide their standard "costs" to develop.
Unless it's a standard that you need to follow by law, it doesn't make sense for the government to be in charge of making it public.
We'd want to pay for that too!
Or we could (And I have always thought this would be helpful) have a FOSS standards forum. Want a standard, make a Git issue, people discuss it for a bit, someone makes a markdown pull request.
It would be pretty sensible for the EU to pay the USB consortium enough money to make the standard free for all EU citizens - I think that one is already free but you get the idea. Especially because the EU wants USB ports to be mandatory on cellphones.
The EU or US could just decide to pay for it. I would guess that this is politically easier to swallow in Europe even though it makes as much if not more sense economically in the US.
