This is very different to the actual topic at hand. The zoo can't be copied
and isn't a piece of digital information (where copying is one of the natural
things that can be done with it).
Even if it can't be considered stealing to copy a CD, it still might be wrong
to not pay for going to the zoo.
I think, that the cartoon was supposed to say that the propaganda around
copying music and all other digitally distributed things is ridiculous. Sure
there has to be a way for artists to make money off of their work, sure there
has to be a market for software.
But copying isn't stealing. If the current market model can't work once
copying is allowed (which is very unlikely anyway, most computer games are
copyable, still they make them and don't go bankrupt...), we need a new
market model. That's all. Not made up fences and artificial digital handcuffs
that give developers or music publishers unjust power over the consumers.
