An issue with 1-3 is that a site could stop the user from copying 
content off the site. We already see a similar thing happening where 
sites cancel the rightclick event to prevent users from doing "view source".

A site could use the copy-event in 3 to always replace the copied 
contents with an empty string (or a string containing some copyright 
statement). Or the site could on every key-press and mouse-click 
cut/copy an empty string to the clipboard.
