The argument for piracy is quite simple: conscience and morality.
The masses simply don't care if a few pirates can't reconcile it with their conscience that the respective provider acts like a piece of shit and treats its customers like shit under their shoe. Those providers just have to make sure that there aren't too many pirates and therefore scrape the shit off the sides of their shoes from time to time.
All the other arguments are tangible. But they are often already essentially solved.
You craft and finish a plan before you walk up the mountain and then stop thinking about the mountain. You don't look up the mountain, just at your steps and the way right before you. The mountain wants you to worry, but if you worry, you loose. So don't look up the mountain and just walk, step by step.
Know that worrying about things like this is like trying to solve an algebra equasion by chewing bubble gum.
