You read what you want to read I guess
Nope, you clearly admitted it would have a negative affect, you simply excused it away as an obsolete model.
See, luckily for the taco vendor anybody who made a business of just giving away tacos would quickly bankrupt themselves for obvious reasons. However, in the gaming industry that doesn't exist. Crackers/pirates can distribute other people's hard work for free for nothing. The end effect is the same though, which is you have the same product available to people for absolutely nothing. This without a doubt cuts into the sales of the people who are actually trying to sell said product (you know, the ones who worked hard to actually create it and deserve the compensation).
That's just one aspect to piracy too, there are other negative affects like having to support pirates (estimated at nearly 30% of support tickets, and is money right out of their pockets). Negative word of mouth due to bad cracks, and all sorts of other stuff related to piracy.
Do I think pirates are evil people? No, certainly not. But the idea their actions when taken in bulk doesn't have a negative effect on this wonderful industry and all the amazing hard working people who make it possible is just idiotic.
Personally if someone said "yeah I pirate I didn't have the money and just wanted to play it", I would at least know I am speaking to a person with their head on straight. The new mentality (yours), however, is just moral debauchery and quite simply dishonest.
