It may be a small point, but...every thing you mentioned gets brought about by private money.
Except the roads.
Toll roads are an abomination, the gas tax should be a sufficient funding vehicle for road construction and maintenance....
What’s next, we pay the military a fee to protect is and our goods first?
(Yes, reductio ad absurdum)
Sort of.

However, toll roads continue to charge tolls long after they are paid for so they end up making money for repairs and updates. Toll roads relieve traffic on the non-toll roads, therefore, those of us who willingly pay tolls to avoid traffic lights or start/stop traffic benefit those who do not pay since we lighten the traffic on those surface roads.
