I suppose if Spaghetti Inc and Olive Garden were in the business of creating and licensing recipes, they would both be in trouble. But they are selling labor and ingredients, which is what people are paying for. Also, pizza and spaghetti have been around a long time and patents don't last forever, so I don't see how this applies.

Maybe a better example would be to explain how drug companies are able to cover the cost of research and development, or how Studio Ghibli is able to invest in animating a movie that anyone can sell. Should everyone provide the full suite of services a business needs in order to earn a profit? That seems like an inefficient way to organize the economy. The mechanical engineer also has to be a marketer or else he doesn't deserve to be paid for an invention? How does that make sense?

> Sure, different inventions work differently. What does that matter?

You cut the sentence that answers the question.
