"Copying is not stealing. Stealing involves me removing property from someone, copying is me making a duplicate of said property with them still having said property."
By that logic counterfeiting isn't stealing.
The attempt to take it into the abstract, remove all context or impose other contexts, doesn't actually help see the problem better. I think with game piracy we are simply stating that:
1. The developer needs to sell copies in order to both continue creating games and earn a living.
2. Anyone who seeks to provide or acquire games and not contribute to the above proposal is stealing from them.
Free copying and distribution of games costs talented people jobs. Right or wrong, the developers are the last to turn a profit on a game. A pirated game comes directly out of their pocket.
