Sounds like treason to me. Earlier someone posted a pdf here about statistical significance and why the present length of copyright is bullshit and a violation of the wording of the consititution. You can't really use the media tax because most people just buy regular media to avoid the extra charge.
Dunno about not using the media tax, but I don't have the facts at my fingertips, so I can't intelligently debate you.
OTOH, the person you are thinking of is, I believe, law professor Lawrence Lessig. IIRC, he was able to use a statistical model to show that the current copyright term gave the copyright holders something like 98% of the benefits of having a copyright in perpetutity. -- That which does not kill me merely prolongs the agony.
