"Cannot invent aything" is a strong statement. You made it; I did not. Yes it is an old fact that the Japanese have perfected the already existing ideas, and that in itself requires innovation. That innovation was marginal (and a lot of marginal increments can produce a large, even infinite integral, as you know), and you cannot possibly compare any of their corporations to our automobile or aviation in their respective infancies.
As to the private property, again, I did not say that it is unique to the U.S. -- you assumed that. The ease of business formation is still unparalleled in the U.S.
What also had in mind is that, placed in the public domain, the servicing of a product acquires feature of a public good. I do not think that, say, N years out, the provision of support for it will not fizzle. I have more confidence that a private good will be provided by the market.
This was a thread about linux and Microsoft. What does the concept of public domain have to do with either of those things? Why would you introduce that concept into this thread?
