Yet with only a personal IPv6 block half the world can't access your resources so that's not a reasonable method at this time. If you control the DNS there's no real need for owning your own IP addresses as you can just change what they point to. That's usually also much faster to do in a pinch than find a new party that will announce your block and convince the old one to stop doing so. That's usually hours if not days in lead time. Though if you truly care enough about it you'll also want your own DNS servers and own gTLD in order to own the whole chain.
