Intellectual property
From Organic Design wiki
The phrase "intellectual property" is considered by many to be useless word vaguely referring to patents, copyright and/or trademarks, which all have very different bodies of law applied to them. However, we purposefully choose to use the phrase to encompass them all because we believe that they all share a single important aspect in common that is putting an artificial limitation onto the propagation of knowledge.
This is the diametrically opposite problem of usury and passive income, because it attempts to limit and fragment the domain of ideas and creativity, which is inherently infinite and unlimited.
