After reading this, please let me know what would be so awful about 100% toll roads.
This makes an easy comparison.
Currently, you pay a gas tax, per kilometer. No-body cares *what* you do with the gas at that point, or where you go. You can drive on freeways, you can commute to work, you can roadtrip across the country, you can just drive around the block for hours on end if you want. The only limit is the physical ability of the roads (expressed as a speed limit).
Conversely, a toll road will charge you for each segment of road. Suddenly, *where* this road is and what it connects to becomes a huge factor. If I own the major route, I can charge more (forcing you to pay or take a longer but cheaper detour) If I own the road that goes past the supermarket, I can charge more for that segment because it's popular (and the limit of what I can charge is "as long as it's cheaper than driving to the next furthest market"). If I own this movie theatre and the road in front of the competition's theatre? I can make it prohibitive for anyone to do business there. Just think how much fun you could have with speed limits. And how much is access to the road in front of your *house* worth?
And if you own a whole lot of roads, you can change speed limits to encourage traffic to go to stores you like/own, and away from competition.
This is the world the ISPs want to live in - they control all your roads, and they want to be able to adjust the toll road pricing so it's "cheaper" to go to their stores instead of their competition.
