For me, I included "beanie draws" in my tags and channel tag as it gives me a slightly better chance at being found if someone just happens to want to look for "Beanie draws" because I told them to search for it.
There's some channels with very generic names, or names that lots of other people have, and if you're trying to get other people to find your channel via word of mouth rather than a direct link, having your channel name can help it be found a little easier I think. I think it's more about helping people find you specifically early on. And for example, if I never use "beanie draws" as a tag, but others tag their videos based on me, with "Beanie draws" competition wise, if someone types "beanie draws" into youtube, they might get other people's videos instead of mine. That's my understanding of it.
