ant8904, do you also believe that every other commodity we use in daily life should only be priced based on cost to produce, and not on the market supply and demand?
Enjoy your long bread lines, Comrade.
For the record, congestion is a cost as well: it's a cost of not having the infrastructure be reliably available. Congestion pricing lowers the cost of congestion by exchanging time for money. In addition, the revenue from proper pricing can be used to subsidize very nice bus service, which is much more progressive than the status quo.
Right now, the highway facility is for all intents and purposes only available to people who own automobiles, with little dribbles of bus service (that gets stuck in traffic) by comparison. People who own automobiles tend to be richer than people who do not own automobiles. Therefore the status quo is regressive. For the vast majority of people, there is a very high priced tollgate on the highway: the cost of owning an automobile.
However, the implementation of congestion pricing and the use of revenue to provide good, high quality bus service, lowers the toll on the highway to that of a bus ticket.
In addition, even if you aren't rich, but rich enough to own a car, then getting stuck in traffic is still a high cost. Possibly even higher a cost than for a richer person. Usually, it is less affluent people who are more time-starved because their jobs are more stressful, and they have less control over their schedule. So perhaps under the status quo, the rich and the poor get stuck in the same traffic, but it may very well hurt the poor more. Regressive, as I said.
But as I said before, it's too-sensible-to-happen because people like you would rather sit, stew and rage in traffic -- and make up ridiculous excuses. Also, I suspect, for many drivers (likely not on this forum) the idea of doing something progressive such as enhanced bus service is distasteful. Might bring the "undesirables" to their community. You know, the usual NIMBY crap.
