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.
