Ten years is an eternity when it comes to software. But yes, software developers (and other people creating things covered under copyright) are overvalued compared to those creating physical things. And that valuation is created entirely due to IP law. How is that fair?

In that case, the value of land is created entirely by property law.

A farmer has the exclusive right to land from the existing fixed supply that the entire world has available to it. He didn't create it and no one else can use it. Whereas a software developer makes something new. Nobody else was deprived of anything pre-existing. Less justification for taking code from a developer than land from a farmer.
