So in that scenario we can produce infinite steaks, right?
Now, people start stealing those steaks because we can produce an infinite amount of them, infinite supply = cost should be zero.
Now, tell me... What's the incentive for the steak producer to continue producing those steaks if people aren't paying for them?
See where I'm going with that?
In the end of doesn't matter if an infinite quantity can be produced "for free", there's people behind the product that pay the price and no matter how you want to justify it, if you don't respect the way the creator wants to give access to their product to people, you have no moral ground to stand on.
I'm not saying people don't do it, I'm saying that trying to justify it to make you feel better about it is pure hypocrisy and just wrong.
