In the extremely unlikely event that happens (provided you pick a registrar whose only service you're using is DNS), then you transfer it to another one, as mandated by ICANN. You're down a week, but everything is fine after that. Quit being contrarian.

It's a bit like getting struck by lightning, you deal with this when it happens if it happens. This is sufficiently unlikely for most people that it's not worth being too concerned about it when other exceedingly more dangerous and pressing matters could be dealt with using that same energy.
