Question

why does the government protect inventors and authors by offering theme patents and copyrights

Answer 1

It is to protect these arising companies from copyright infringement and creates value to these investments and items they may buy or sell. Without this, there would be no value and the economic system could collapse. It protects companies and allows companies to be independent and significant rather than similar clones to other companies. Other theories such as social-Darwinism, capitalism, and laissez-faire economics fall into this.
