Hmm ... nah. The internet would have happened anyway. Also, we owe its growth to plenty of ISPs everywhere and quite possibly ... piracy and porn.
Even if it was true and the government single handedly created the whole www, that shouldn't be a carte blanche to just waste money that could otherwise be invested in a better way.
Also your bit about YC, YC is private money, they could throw all of it into the ocean and I wouldn't bat an eye. The government, however, takes almost half of what I make, for sure I'd like to know, with unprecedented detail, where and why my money is going to.
You couldn't be more wrong if you tried to, lol.
