Copyright is an intellectual property right, firmly grounded in property law doctrine–you are probably thinking of trademark, which is rooted in consumer protection law, or likeness rights which have their roots in privacy law.

First of all, "Intellectual property[sic]" is a not a thing. There are copyrights, patents, trademarks, and trade secrets, but they are all significantly different from each other. Trying to lump them together under a single term is disingenuous at best, and using the word "property" in that term is biased loaded language.

Second, copyright cannot be a property right because ideas cannot be property. In fact, ideas are essentially the opposite of property, as Thomas Jefferson once pointed out:

it would be curious then if an idea, the fugitive fermentation of an individual brain, could, of natural right, be claimed in exclusive and stable property. if nature has made any one thing less susceptible, than all others, of exclusive property, it is the action of the thinking power called an Idea; which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the reciever cannot dispossess himself of it. it’s peculiar character too is that no one possesses the less, because every other possesses the whole of it. he who recieves an idea from me, recieves instruction himself, without lessening mine; as he who lights his taper at mine, recieves light without darkening me.

What copyright actually is, is a temporary monopoly granted at the whim of Congress. It's a license, not a right.

• A property right is a thing the owner is entitled to, and a natural right. In contrast, a copyright is an artificial construct invented as a power of Congress, and granted with the express purpose "to promote the progress of science and the useful arts," not because the creator of the work somehow deserved it.
• Ownership of a piece of property exists in perpetuity until it is sold and cannot be taken from the owner without "just compensation." In contrast, copyright exists explicitly "for limited times" and then it expires and the work reverts to the Public Domain.
