Major cities of the world have adopted "congestion pricing" in which cars pay a toll to enter the core of the city during daylight hours. Congestion pricing is also used to regulate demand by businesses for electricity. During the day when electricity is in high demand, many businesses pay a "demand" fee in addition to the regular charge for electricity. Why is the Internet any different?

Some argue the Internet is different from highways or other physical assets and resources because supply is practically infinite, and the cost of adding another user whether a heavy user or light user is nearly zero.

Some argue that Internet bandwidth and resources are finite, and that there are real costs involved when adding millions of "heavy hitter" users. One cost is a slow$-$down in the transmission of email, greater Internet latency, and potentially major "brown outs" of the Internet which in fact have occurred when usage peaks $($say during presidential nomination ceremonies or the Super Bowl$).$

Both of the above,

Neither of the above.
