Another value in consistency is that when people are browsing aimlessly, they know when they can check your channel for new content. If I check some channel for new content a few times and there is none (and no indication of any coming), I will simply forget about it. Not intentionally. Someone else who posts predictably will have captured my idle time.
As my sibling says, this may be how some users use youtube, generally these views ("channel page views" is the term used in the analytics) are a small minority of overall views.
In fact, this sort of behavior you're talking about is one of the reasons why "the algorithm" is a thing. If there's something you'd like to watch, but you've forgotten about it, it's YouTube's job to surface it to you, even if you've forgotten. This is one of the reasons why browse is the default view and not your subscribers feed, for example.
