Piracy isn't all bad. Especially when it enables:
1. Try before you buy
2. Backup of games
You could argue that renting is the same as trying before you buy, but in my mind renting is just as bad as piracy. Only a fragment of the income earned on rented games ever goes to the content maker. Afterwards, the game is sold as used.
The backup argument stands for itself. You're allowed to make backups of your own games, but content makers make it extremely hard. Pirates to the rescue, helping the little guy.
Sure, some people pirate and never buy. But most these people were never buyers in the first place. It's a minority who would buy a game, if they couldn't pirate it. Most who cannot pirate something, to avoid paying for it, simply won't bother with it at all.
Thus it makes sense for companies to focus on their actual CUSTOMERS, instead of this crazy idea that piracy somehow matters in any significant way.
People only have a certain amount of disposable income. It would be insanity to assume that eliminating the ability to pirate suddenly would turn the Asian pirate customers into paying customers. Most people who pirate simply cannot afford it. The same goes for a lot of western pirates too, maybe with the exception of kids living at home, mooching off their parents, who pirate because it's "cool"
