It's a conspiracy rich. The government is going to copy everyone's work and claim it as their own.
(ummm...don't they do this already)
You're right though, it is important that people are given credit for their work. I just hope no one that takes this issue seriously has ever downloaded music illegally online etc. Or copied someone else's answer on a test, or presented as their own, an idea they heard from someone else.
I guess it's a part of human nature to cheat and steal and lie. That's why these laws are required.
