Obviously you and I have rather divergent understandings of the pirate culture. We'll have to agree to disagree on the idea that piracy will not fall dramatically as the price lowers. Give a kid 60 bucks a week for an allowance, and he'll never pirate. People naturally prefer to do things legally if they can. $60 games make that decision harder for a LOT of people.
Now, to your point about lowering the price not being worth fighting piracy, well, I would challenge your idea that if that is, in fact, true, then piracy isn't much of a problem at all. There are upsides to piracy of software of course. Word of mouth advertising being a major one. Piracy is effectively the Black Market of software. And just like the Black Market for so many other things, the legitimate price of a good or service being too high causes that market demand to get satisfied in a different manner. Abortions, Designer Purses, Software. All are cheaper on the black market, and with each you are taking your chance that you'll get ripped off.
