I've already pointed out why there wouldn't be toll roads everywhere. In fact, out of all the business models available for roads it seems like the worst one available to me. But then I am looking at it from a business standpoint. Not a position where I'm freaking out about the possibility of "no govt, no roads".
If you have a road you want to encourage throughput on it. Otherwise, what's the point?
Like the way that shopping centres which maintain the roads and parking spaces in their car park complain about freeloaders, you mean?
It doesn't matter to them because the costs of maintaining them are so small compared to the profits they make. They don't want to scare away potential future customers by complaining about the "freeloaders".
