I didn't say it wasn't. I said that if I photocopy your book, YOU STILL HAVE YOUR BOOK. If I copy your software, YOU STILL HAVE YOUR SOFTWARE.
If I steal them, you no longer have them. Thats what I meant by "loss." Not indirect revenue considerations.
As far as I can tell, there is absolutely no way to enforce IP more effectively that doesn't result in enormous costs/dead-weight loss (in this case born by the taxpayer). We already have enough enforcement that entertainment industry is very profitable. The average taxpayer is enormously entertained: we are suffering no loss of entertainment product.
So, why should I (as a taxpayer) have to pay more taxes AND deal with the annoyances of a potentially fragmented internet FOR NO BENEFIT?
The source's numbers are hokey. Keep in mind that when someone downloads a movie instead of paying for it, they eventually spend that $1 (I think thats the redbox rate?) somewhere else. Piracy redistributes resources, it doesn't remove them from existence. When I watch a movie my neighbor rented, I don't simultaneously set my cash on fire. I use it to buy popcorn or chips or whatever I'm bringing over. Less jobs for redbox, perhaps, more jobs for the grocery store.
