You also don't need to paint an entire a peer to peer community with the worst actors on it. There are plenty of normal content creators and instances that are not overrun with that content (see https://tilvids.com/videos/trending)

Also backing up your videos locally will not do anything for helping your fans get access to your content, you will still need to re-host it somewhere. Having it on peer-tube means if your account gets frozen/banned over some bullshit, you can just point your fans to your peer tube channel.
