Property implies ownership and ownership implies absolute control. Intellectual property takes the form of copyrights, trademarks, and patents. If you create a song and are granted a copyright, does that mean you own it? No. The copyright is granted by a government agency. The agency dictates the terms of the copyright. Usually it dictates limitations such as a time frame (for example, your copyright is only valid for so many years). The same is true of trademarks and patents. Receiving a copyright does not grant absolute control, it grants limited controls. Under the concept of intellectual property the only ownership that can be said to exist is government ownership over all creative works.

Things are even worse for consumers. Consider Nintendo's recent announcement:

For nearly three years now, creators who wanted to make money from videos that included footage of Nintendo games had to go through the onerous approval and content requirements of the Nintendo Creators Program, which also gave Nintendo a 30 percent cut of any ad revenues. Today, Nintendo announced it would be halting that program at the end of the year, in favor of a new set of "basic rules" for video creators. If those rules are followed, Nintendo now says, "we will not object to your use of gameplay footage and/or screenshots captured from games for which Nintendo owns the copyright."
