The thing is, traffic is not a zero sum game. 100,000 people trying to get to drive down one road at the same time cuts the speed to a crawl and it may take each them 2 hours to travel 15 miles. 100,000 people driving down the exact same road, but spread out such that 10,000 people use the road every half-hour, and suddenly the drive only takes 20 minutes.
There are measurable benefits to forcing stupid people to not do stupid things. If money is the one stick that works to get the stupid people to do what is needed, then we must use money, in the form of a fee.
Your logic works on the assumption that those people don't actually have to be somewhere at the same time. If you have 100,000 people that need to get to point B at about the same time, and it will still be faster than taking an alternative route, they will pony up.
I used to live in NW Indiana. I worked in downtown Chicago. I could take 94 all the way in, or I could take 41 up to the skyway, fork over $3.50 and knock out 20 min on my commute. In this case, I'm the opposite as I'd gladly fork it over if it benefits me in time. As they say, time is money.
Now imagine if they put a toll on the Ford...
A similar thing happened many years ago in SoCal. They opened a stretch from south of the 405, off the 5 if I recall that was a bypass. I don't remember where it went anymore but it too was a toll and barely a soul was on the thing.
Adding a toll will only work if they do it everywhere.
But...here's the thing. The infrastructure in most cities aren't setup for public transportation. And by that I mean rail. Yeah, in places like Chicago it exists, but compared to NY, London, Paris, Singapore...can't touch it. America is a driving nation. Everything was built on it, especially since the 50s.
If you want to ease congestion, build better, longer lasting roads. Build better interchanges. Build secondary, smaller capacity systems for national traffic (ie completely bypassing major cities with only emergency access). Build better merges and double wide exchange ramps.
There's so much that can be done. Simple tossing a charge it won't fix it.
