Copyright infringement is not piracy. Copyright infringement is copying and/or distributing copyright material. Piracy is selling copyright material without permission. People used to sell fake-DVDs. That is piracy. The vast majority of those who engage in copyright infringement do not profit from it, often quite the opposite.
Equating downloading a copy of a file to theft is quite ridiculous. One deprives someone of the use of the object in question, the other merely duplicates an electronic file. This is claimed to be a loss but that is only true if the infringer would otherwise always have purchased a copy. It is reasonable to conclude that this is not the case in all instances.
I really wish people would think about this issue in a somewhat rational fashion without swallowing wholesale the propaganda. There is a fundamental difference between actual property and so-called intellectual property. One has a finite existence, the other less so.
