It does also have situations where people go "Hey, this toll bridge was built 50 years ago, surely the tolls should be abolished" and the people who built the bridge are like "Nope. See, here's the press about it 50 years ago saying what a great idea it is to have the tolls be slightly lower but perpetual". Feel free to build a time machine and go tell your past selves that's not a great idea after all.
But well, nothing is forever. In five hundred years that perpetual toll on a road is obsolete because hardly anybody owns a private vehicle so the toll mostly just moves (local) government money from one pile (funding transport) to another (build infrastructure) and it's not a very efficient way to do that. Or the bridge falls down and its replacement doesn't have a toll because people were sick of tolls. Nothing is forever.
