alt Hacker NewsEarly copyright was a take on property rights, applied to supposed labour of the soul and subsequent ownership of its fruits.
Copyright stems from the 15-1600s, while utilitarianism is a mid-1800s kind of thing. The move from explicitly religious and natural rights motivations to language about "intellect" and hedonism is rather late, and I expect it to be tied to an atheist and utilitarian influence from socialist movements.
The first modern copyright law dates to 1709, and was most certainly not a "take on property rights". Neither were pre-Statute of Anne monopoly grants.
I can find nothing to suggest a "religious and natural rights" motivation, nor any language about "intellect and hedonism".
Statute of Anne - which specifically gives a utilitarian reason 150 years before your "mid-1800s" estimate also predates socialism by a similar amount of time, and dates to a time were there certainly wasn't any major atheist influence either, so this is utterly ahistorical nonsense.
