People will never just spontaneously realize you exist and on their own seek out the media you produce.

They have to discover you somehow. The YouTube Algorithm is at least partially concerned with enabling people who would like your channel to discover it.

Regardless of how well you think YouTube does that, you have to admit it's not exactly a simple thing to do. YouTube is trying to maximize ad revenue by maximizing watch time. They are not trying to evenly distribute viewer attention among "worthy" channels.
