I don’t know how the original poster meant it, but one possible way to interpret it (which is coincidentally my opinion) is that the concept of intellectual property is a scam, but the underlying actual legal concepts are not. Meaning, the law defines protections for copyrights, trademarks, patents, and trade secrets, and each of those has their uses and are generally not “scams,” but mixing them all together and packaging them up into this thing called intellectual property (which has no actual legal basis for its existence) is the scam. Does that make sense?
