Okay, let's take away your freedom to travel, since you've disparaged mine, and discuss this again later when you've been cooped up in your house for about 100 days and unable to leave home.
Smartypants. See how you like it when the shoe's on the other foot. Pinches, huh?
Oh, and the cite is the Ninth Amendment, which specifies that freedom is the default condition in all things not invaded by the legislature's lawmaking power. That's the concept that Bob Bork got hosed on, when he was up for confirmation as an Associate Justice.
Under those guidelines, tolls could only be charged on roads where travelers were given the option of using a parallel "free" road. So the choice for a motorist would be to: 1) pay a toll for a faster trip; or 2) "pay" (in the form of lost time) for a slower trip.
This is all just a silly argument over an undeniable fact . . . that public infrastructure will always be used to excess when it is "free" to the users.
