Patents and copyright are both IP. Feel free to replace “copyright” with “IP” in my comment. Do you not agree that IP laws are related to the explosion of innovation and creativity in the last few hundred years in the Western world?

Furthermore, claiming “X is not natural” is never a valid argument. Humans are part of nature, whatever we do is as well by extension. The line between natural and unnatural inevitably ends up being the line between what you like and what you don’t like.

The need to eat is as much a natural law as higher human needs—unless you believe we should abandon all progress and revert to pre-civilization times.

IP laws ensure that you have a say in the future of the product of your work, can possibly monetise it, etc., which means a creative 1) can fulfil your need to eat (individual benefit), and 2) has an incentive to create it in the first place (societal benefit).

In the last few hundred years intellectual property, not physical property, is increasingly the product of our work and creative activities. Believing that physical artifacts we create deserve protection against theft while intellectual property we create doesn’t needs a lot of explanation.
