See my point about stealing Lyn Alden's book... you would not only be stealing the profits from book sales but also be stealing the clout and public prestige from conceiving those new ideas.
People respond to incentives... take away the incentives to invent and you will get less inventions. Running research and development in the 21st century is unbelievable expensive and IP and royalties is how these ventures get funded; thinking it will happen anyway if you allow blatant plagiarism and theft of intellectual property if sophomoric at best.
