Nah, I don't think that's her concern. I think the concern is stopping people who shouldn't know or have the resources to make it, but do anyway (meta/powergaming).
If somebody works hard and has the ic means and capability of figuring out a competitors recipe, they still don't get to call it the same thing. I can't legally figure out coke's recipe and sell a product named coke. I can figure out a very similar recipe and call it Bill's cola. But the makers of competitive products, like pepsi, have the knowledge and resources to make a coke like product. So if somebody figures out queensport brew, and does so ic, they can make a similar product. But making the same thing and calling it the same thing is against the rules ic, just like it is against the law irl. There would be ic consequences if caught, just like counterfeiting. If not legitimately sourced, there would be meta/powergaming violations. There is a real concern for confusion of the source of props, and the rules should protect and incentivize people who make the products legitimately. Thus, my opinion is legit ic counterfeiting should only be attempted with the distinct understanding of ic consequences.
This goes back to my dont be a dick comment, though. Why would we counterfeit if we have the resources already to make our own distinct product.
