I agree with you on talking being faster than typing. Having said that, I feel that this is more of a reason for me (and, I assume, for the top commenter) to counterargue that it's the youtuber's job to distill the message down to its important parts. Speaking is definitely faster for him, but it requires a bigger compromise on my part - whatever amount of time he saved requires me to spend ~15 minutes for something that can be told in one.
Or to put it bluntly: if he can't take the time to streamline his message then I don't have the time to listen to all of it just in case it gets interesting at some point.
His youtube channel started out as him just rambling to the camera about his problems and how absurd it is. It's grown since then as people have been following it. His channel is basically that, him talking to the camera about problems he sees in the world. He does what he wants with the channel. I'm sure he's not going to change that format anytime soon just because he has more followers.
If you want to watch it sure. If not then that's fine. But he doesn't have to streamline anything and that might be his loss, but in the end it's his channel to do what he wishes.
