>Copy protection, also known as content protection, copy prevention and copy restriction, is any measure to enforce copyright by preventing the reproduction of software, films, music, and other media.

I don't see much point in making the theoretical argument of "nothing is unhackable". The point of protection isn't to make some absolute defense, it's to mitigate low effort thieves. Any house can bypass a lock by using a cheap hammer on a window, but I'd still call a house lock a "lock".
