The copying of media dates pretty far back, though before it wasn't always wrong to do. Since the first copyright law, things have changed to call it 'Theft', and while it has a similar harm to it. It doesn't hit the definition.

Copying by itself is not wrong. if someone copies my laptop's specs and OS. It doesn't harm me at all. If they copied my data as well, now it's wrong. If I was intending to sell my laptop (deprived of all my data) and someone copies it then it's annoying but I can still sell it to the next guy. But if said copier, copies it for everyone then my laptop is worthless. Though it never left my hands, I was deprived of its value much like theft.

Externality seems to describe it best. The individual never directly touched anything and never had malicious intent however I was affected by their actions.
'Copying with negative externality' doesn't really roll off the tongue very well though. Is there a better term for this?

To layer on the question further, is ai scraping the artstyle of an artist negative externality? A friend of mine trained an ai model to near perfectly mimic his chosen artist's style. He used to commission and give money but now he doesn't have to, now he can print away his anime waifu without waiting, without needing to go back and forth with artist to get the character just right and for free! (well he's paying for servers so not quite free). Even worse damage if he releases this model online to others.

What do you think anons? What kind of seven seas have you plundered in your years?
Is it wrong to copy files and artstyles? In basic morality it harms another. Admitting-ly I do it all time for movies and games.
