Except that, as the pencil proves, it's not a fallacy; it's how the market works.
Tell me where the pencil explains how innovators are encouraged to innovate.
Yes, and who could have imagined superhighways, the internet, and modern medical technology 100 years ago?
Indeed. 100 years ago people had just as much evidence that such things would be invented as you have of a free market intellectual 'property' protection system. That is: absolutely none at all. 100 years ago people had no reason to assume such things would one day exist, and we now have no reason to assume that thing of yours will exist. You can claim as much as you want that 'the free market will find a way' but you don't really know that it will.
I'm sure 100 years ago some people had ideas that never became reality and we now know likely never will... Like time machines, or gravity shielding materials like Cavorite. Just because you can show that the free market gave us many wonderful inventions, does not prove that it will give us time machines and cavorite as well.
There is just as much evidence as there is for the sun rising tomorrow: because it always has, and we know of a mechanism how it can work.
You have not shown a mechanism of the problem might be solved, you have only shown a mechanism that is capable of solving problems: the free market. That does not prove that the free market can solve that particular problem (if we assume it is one).
They demand that if I can't provide specifics of how a problem can be solved, that is evidence that the market cannot solve it and therefore we need government intervention.
No, the
ask whether you have any specifics of how a problem can be solved, and if don't have such specifics
you have no evidence that it can be solved with the free market and without government intervention.
Asking a question is not making a claim. So asking how something can be done without government intervention is not making a claim that it cannot be done without government intervention. After all: you might be able to answer the question and explain how it can be done without government intervention, disproving that it cannot be done.
But since you cannot explain how it can be done without government intervention, the possibility that it could be impossible remains.
You haven't and you have said so yourself: you can't provide
any specifics.
It only results in the questions getting more specific.
As soon as questions become so specific that you cannot answer them, it is time to say that you don't know
and also admit that something may be uncertain.
It is okay to have faith that something can and will be solved, but it is not okay to claim that a nice parable about a pencil
proves that it will.
