Well, if you look up the definition of stealing, it's basically 'taking another person's property without permission or legal right with no intention to return it'
Essentially, that's what piracy is - Taking someone's property without legal right (paying for it) and with no intention to return it. It doesn't necessarily mean the person has to physically LOSE what you took. You're essentially saying that stealing is only limited to any form of product that incurs recurring cost, is meant for personal (not business) loss and isn't harmful if you never had the intention to spend on the item in the first place.
Companies did invest money into games, shows, products too - and by pirating it, they lose out on finances that could potentially determine whether the company actually makes a loss that year or barely breaks even. Not every business and product is profiting large gains that their CEO drives around in a Ferrari and sips Malibu off his private island. Sure, you may say that if the product isn't available in your country, what's the harm; but face it, with the internet now, everything is available everywhere. So, basically if I can afford it and it's available in my country, I SHOULD pay for the same product that YOU get to enjoy for free?
If everyone thought the same way as you, then all companies would end up failing because who would pay for a company's product then, if all of us rather not have the intention of spending in the first place, and just pirate it. Well, if we live in a world by your logic, then say goodbye to Walking Dead and every other show or game you love because they'd all go bankrupt.
