He took more of a position of not being a gatekeeper. It's not for him to say if Louis should do stand up or not, he's free to do what he wants. If you don't want to see him doing stand up then don't watch.
I don't see anything wrong with the answer.
It's not just Bill "recusing himself" from a gatekeeper position, I think it's an awareness that stand-up has little in the way of gatekeepers for those who are able to draw audiences. All anyone can do is to take a position and persuade people as best they can, but it's fundamentally a conversation with the potential audience.
For good or for bad, when your chosen medium is literally just public speaking, there's little anyone can do to stop him if audiences choose to see him. Even if you went after clubs, anyone can rent a theater, or a public fire hall, or some kind of venue and talk.
So the practical reality is that his career is in the hands of audiences, and the conversation has to be a persuasive one with the audiences themselves. And, of course, you simply won't convince everyone. It's very unlikely Louis will ever achieve the kind of success he had in the past, but it's just as unlikely that you'll convince absolutely everyone not to support him.
That may not be a satisfying conclusion for some, but it's hopefully enough to make people in his position more thoughtful going forward, and that's honestly the only thing I care about. I don't really believe in karma or a sense that retributive justice needs to be meted out at the right levels to restore balance. I just want people to learn and do less harm and be better in the future, and I'm hopeful this still serves as a lesson.
