To understand that, you really need to go through the thought experiment in the video link I sent you. It's like giving control of a complex machine to a child. There's no way to make all the right decisions, let alone enough to keep the boat afloat for long enough to avoid mass democide or severe persecution against the rights of the individual. Take for example the Falun Dafa practitioners in China who have their organs confiscated for the "good of the many." The key is to go through this thought experiment. It sold me 100% on the knowledge problem which I wasn't even aware existed prior to watching it.
