I would love to hear your explanation on why piracy is not wrong! That was the exact purpose of the question, so others would share their views on the matter and I would have an enlightened view.

Flip the question on its head: why is piracy considered wrong? What is the specific, provable harm that it does? Is it true to say that there is no benefit to it? If there is a benefit, is the benefit to society greater than the harm to the creator? If there is no benefit to it, why does it happen? Does the cost of fighting it outweigh the harm done? What is the cost of fighting the fight if you disagree?
