The article attempts to make logical arguments from false premises.
* What makes evaluating regulations so difficult is that the benefits are usually readily apparent ... but the costs are much more difficult to quantify Why should that be so? The actual costs of implementing and conforming to a regulation are easier to measure than the benefits. The benefit of NN is harder to quantify than the cost of enforced nondiscrimination.
future innovations ... are far more difficult to calculate Predictions are hard, especially about the future. If some future innovations are difficult to predict consequent to a regulation, others are hard to predict in its absence.
* regulation always has a cost far greater than what we can see at the moment it is enacted Why should that be so? Because we can't know the future? If that's the case, it's equally true for benefits: we can't know the full benefit of a regulation, either, because not all the behaviors it forestalls have been invented yet.
It has been estimated that many EPA regulations have benefits worth 100 times their cost. Those benefits far exceed EPA's original estimates.
A regulation is a law. We hear a lot about them as "bad" because corporations have the money and time to complain about them in the press and to congress. They say the problem is costs, but when it comes to intangible goods like banking and communications, the "problem" is often the regulator's interference with the corporation's ability to exploit imperfect information. If you don't think your phone company or credit card is two steps ahead of you, read your terms of agreement sometime.
Good regulations squeeze out bad actors. Worldcom did significant damage to AT&T and their customers: by publishing fraudulent financials, it pushed AT&T to make deep cuts to services that -- by honest accounting -- were profitable and competitively priced.
A good contemporary example is airline pricing. Not long ago, the price you paid for you ticket was the price for getting from A to B. Then the airlines started charging for drinks, then food, and now bags. The real price can be $100 more than the published price. When searching for fares, there's no way to look for an "all in" price, so all airlines are forced into this deceptive model. Only regulation could successfully return us to a normal system where the price is the price.
The Internet exists because of taxpayer-sponsored research to create standards and place them in the public domain. Anyone who used MCI Mail or Compuserv or Prodigy knows what a privatized Internet would look like.
The idea that the telephone company (or cable company) should be allowed to determine, in any way, how we use their service or what we use their service for has no analog in any other industry, which is why every supporting argument is specious or disingenuous or just false.
