For the sake of argument, I'm contemplating the idea of counterfeiting Mona Lisa, as you say. I can't see anything wrong with it if it's for my own personal pleasure and I'm not hurting anyone.

Don't forget copyright is a human construct and is far from being perfect. Also the amount of years after which art becomes public is human made and totally arbitrary. Why not 2 years? Why not 500 years? Ethics are not in the game here, I'm afraid. I'd like you to reply but please, restrain yourself from insults this time. Thanks
