it's not enough to say "IP law doesn't prevent theft" (<- true) we must also stress that IP law enables and causes theft and then legally bars the original creators from using their creations, until corporations are mass producing the IP for immense profit while the original creators die in poverty (<- also very extremely true!!!)
like I could not care even a little bit about "IP theft". you can not steal a concept the way you can steal a car just by copying someone. that isn't a real thing you can do. I don't care about this.
but what I do care about is comic book writers dying broke and hungry while disney pumps out another $1billion military propaganda MCU film using their characters (labor they were payed comparatively nothing for).
what I care about is Gary Bowser paying nintendo 30% of his income for the rest of his life, just because he was pirating games.
IP law is not just some kind of hypothetical ideal. IP law is a law, and it hurts people in real material ways, while helping corporations further stuff their pockets. if you support IP law, if you're some kind of pro-IP activist, you are perpetuating real harm that hurts real people while helping corporations gain more and more power. your motivations do not negate this. and if anything your motivations just make you look like a useful idiot.
