The marginal-cost-is-all argument also fails to take into account copyright law, which essentially grants each new work a sort of miniature monopoly. If I write a book about something, you can’t republish it unless I give the okay, or unless it’s 70 years after I kick the bucket and the copyright expires. You can argue about whether copyrights are too long or too restrictive, but we grant them so creators and investors do the creating and investing they otherwise would do much less of if anyone could profit off their work. Just because a product is digital doesn’t mean it’s infinitely abundant—as long as the law is enforced.
