Back to discussion, I agree that saving money could apply to almost anything. However my first point is that, in my opinion, there's a material difference between digital piracy and stealing a car. If I possess a car, nobody else can own it. However with digital media, I'm making a copy of something that has zero impact on anybody else's ability to own their own copy of that data. The only thing that's lost is my physical storage space that could've stored something else, but that's my call to make.
A second point is that I mainly pirate things I wouldn't have bought otherwise. I still watch movies in theaters because I can't pirate a theater experience (AMC A-list is great if you enjoy watching in the theaters IMO), I still buy modern games because I'm extremely cautious when it comes to running executables.
A third point is that ethically, I consider supporting a mega-corporation like Amazon worse than committing piracy. Mega-corporations commit much more morally heinous actions, and at an enormously greater scale, than an average pirate would ever commit. In my opinion, the moral sin is not that pirates commit piracy, it's that mega-corporations have been given almost free rein to shape and exploit our society as they see fit
Pay $10,000 for a KIA that can only goto McDonalds and Burger King, then buy a $15,000 chevy that's the only car that works on the road to to work, then pay $5,000 for a ford that is the only vehicle that will take you to Burger King and the Apple store, but it stops every 5 minutes to show you the same ad repeated 3 times, and the only car that will take you to grandms's house is $30,000 and for some reason it requires 12 cars worth of parking spots. Taco Bell will only be accepting Mazdas starting in August, so you've got to decide what you want to do about that. Also there's no cars you can buy at any price that can go anywhere you want. Nobody sells the lamborgini you can drive anywhere for free.
Anyways, that's why pirating is good.
