There are people that do it tastefully and people that are creative and interesting. If they can’t be interesting and descriptive to some extent then they’re probably not people I want to engage with.
And honestly, the titles were so bland they were almost snarky, and I never felt they were justified for the creators I watch. They were so laconic they were often barely informative anyway, because the flavour was gone. I think that’s because the people who have a good sense for editorialising aren’t going around writing aggressively literal titles all the time. The dearrow ecosystem is subject to algorithmic selection too, and it selects for boring.
Authority is usually understood by anarchists as a component of hierarchy. I’d be interested to hear your definition that doesn’t make it hierarchical.
And there are ways of enforcing rules that don’t require authority, like diffuse sanctions, essentially community-based enforcement.
There’s a whole school of anti-carceral justice thought that deals with this.
