He didn't go deep enough into the history of copyright to understand what copyright is really for. The original purpose of copyright has been so distorted by the lobbying and propagandizing power of various industries, that most lawmakers don't even know what it's really for.
Everyone thinks, like this article's writer that it's to give "property rights" to content creators, so that they can protect their "intellectual property."
What it's really therefore is to encourage the creation of creative works for the benefit of the greater good of the people (the greater good of the people should be behind all laws in a supposed democracy right?). It's purpose is to enrich a very important and undervalued concept called "the public domain." The temporary monopoly, is an incentive to content creators to create works which will ultimately enrich the public domain, at least in theory.
The Public Domain has been completely destroyed by this process of lobbying and propagandizing corporate desires into legislation. Much of the significant creative work of the past century is caught up in it, even if it's not available to the public (this is more common than you might think.)
So, let's always remember that the people in general are a much larger and more important group than the content creators.
Copyright is a privilege granted by the people. The fact that "right" is part of the word I think is a bit misleading. It's not an inalienable right like life and liberty, as many people, this author included seem to not understand.
