Before the net, if you wanted to send a copy of something that was protected under the copyright monopoly, it was an absolute given that you could do so. You would send that copy in the mail without a single thought of repercussions. You could send copies of drawings, you could send mixtapes of music, you could send copied movies. The reason for this was simple: the right to communicate in private is a fundamental human right, and the copyright monopoly is a commercial distribution monopoly that carries significantly less weight.
