This in particular stood out to me. Reductio ad absurdum is, in fact, a valid method of argument. He is pointing out that if you were to be consistent, the pretty girl should be paid money just for walking around. If you really want, let’s make her a model, so that she actually makes her living from having people look at her. Her walking around is her providing her normal service without charging anyone. If we were to follow your logic, this would be a market inefficiency. Perhaps you are okay with that, in which case your opinions would be internally consistent. But most people would probably think that it is a ridiculous notion to say that the model not being paid while walking around is inefficient.
The point is that all utility is impossible to measure between individuals. You cannot know if the pain caused to the one guy outweighs the pleasure gained by the 20 hungry people being fed. It’s the same with bridges. It’s not just the number of bridges, but how long they are, where they are located, what they are constructed with, how wide they are, etc. Perhaps the first bridge is really well built and sturdy. Maybe the second one has only enough room for one lane, but it’s enough to supplement the first bridge so as to reduce traffic congestion. We really just don’t know. Maybe having more bridges is good for when tourists come to town, and during the off season they are superfluous. Again, we just don’t know.
Not around here! On a more serious note, the point of us making modifications to your examples is to demonstrate that they are incomplete examples. You could make up an example where you know absolutely all the variables and whatnot, so that you could know what should be done. But this is impossible in the real world, and that is what the calculation problem is. You can’t really say that one bridge is the optimal amount of bridges in your example. You don’t even know how wide or long it is or what materials it is made out of. And I’m sure there are far more variables than those three.
Okay, now I’m going to respond to your earlier response to me:
Well, NASA is funded at wider dispersed costs. The United States Postal Service is funded at wider dispersed costs. But we can see that the USPS is so inefficient that there are numerous competitors out there, and if it were legal to compete with regular mail, I’m sure that there would be more companies competing in that regard too! The problem of these widely dispersed costs is that the people who directly use the roads (for our example instead of the USPS) don’t get to spend the money where they want! There are potholes in my town, and it’s a nice town. It’s actually known in the area for its ridiculously bad potholes. If people were responsible for their roads instead (for example), I bet there would not be as many potholes. Anyway, the point is that widely dispersed costs does not mean that the government will do it better than a private solution.
Well, my solution was actually not that different from what the government does now. If you want to go to public school, you need to have certain vaccinations. People in this current system are not all getting vaccines. I wouldn’t be surprised if this were rarer with a free market solution. Perhaps instead of not being able to go to schools, maybe malls (the horror!) would also require vaccines. Who knows?
The beekeeper is being paid full value for his labor. Nobody values the extra stuff enough to pay him for it. It’s like when people give out free samples. Sure, no one is paying for the samples, but the business is doing this so that more people will buy the product. Are free samples also market inefficiencies? If so, I don’t see how the phrase “market inefficiency” is a meaningful phrase. But, in regards to the beekeeper, just because he isn’t being paid does not mean he should be.
You are missing the point. You can’t argue for something to be called a natural monopoly if you don’t know if it is one. Maybe natural monopoly theory is logically consistent, and maybe it isn’t. But it makes no sense to call something a natural monopoly and then treat it like one if you cannot know if it is one. Furthermore, maybe there is a natural monopoly in an area for 5 years, and then on the 6th year, a competitor comes to town. What then? What if it were 5 months, and then the competitor came on the 6th month? When you start using government to control these “natural monopolies”, you no longer are able to know if it would remain a natural monopoly.
Answered this earlier in this post.
Ditto to the above.
