The reason why private businesses don't take care of clean water or paved roads is because the government forbids that and a lot of other things. If a private business were allowed to take care of that stuff it would be done with better quality and lower cost. Governments have never been incentivized to keep costs down. If something ends up costing more they just raise taxes. That would make us even more prosperous.
Broadband internet is NOT provided by the government. It never was. It is 100% private businesses.
Prosperity NEVER comes through the government, it comes in spite of government. Governments, all governments are only good at 3 things, killing, stealing and enslaving. After that they completely suck. They costs us far too much.
