I think you are ignoring the sense of space Mastodon gives for replies. It gives a sense that they are a part of a discussion within a digital space defined by the original post. The original poster should have some say over their sense of safety in the digital space of their own posts, and replies by blocked individuals should be disassociated from the post and not part of that digital space anymore. That's not destructive. It's not taking over another account or instance, it's taking control over your own account and the digital space Mastodon creates around it.
