This is not just about backups; this is the reason why I keep my mail on my own domain. ( It could by my own domain on gmail; it's not, but that a slightly different story ) This way I can move it to another company, alter DNS, do whatever I want with it to fix an issue. When you're relying on a company you cannot circumvent in a situation like this (xyz@gmail.com as primary address), you might end up not being able to use your primary account, which might effect your business. EDIT: I'm not going to address the problems with the DNS system itself, which is similarly flawed - you are only leasing a domain, not owning it, and the company maintaining it has the power over it. In theory, this could have been addressed with .onion IDs, but those are impossible to remember and with namecoin's .bit, bit this is not supported by enough real life DNS systems, so there is no alternative to that (yet).
