Did I ever say no regulation? No, I think things like pollution regulations are in general very good (I only say "in general" since there probably times when they've been taken too far -- using the Clean Air Act for CO2 is NOT one of them).
I think I'm generally far more for copyright than most of the (seemingly pro-piracy) posters on slashdot.
OK, I didn't know the term "deadweight loss" before, and I can see how that can cause problems.. I still don't think it should necessarily be regulated in "normal" market conditions. (I think de facto government sanctioned monopolies, e.g. cable companies or things that use limited spectrum, should be regulated MORE than they are now.)
