I believe that if you can’t make your product “copy-paste proof”, like what bitcoin does, any attempts of protecting it from copy pasting would only end up in a net loss either for you or for the society overall.
I do not imply that we should immediately break the current system and force everyone to make everything free. I’m saying that raising a culture in people all over the world where everyone rewards any useful received information will benefit the world and potentially make intellectual property unnecessary (to defend).
