... and there is where it falls apart. Sooner or later, "someone" is going to do something Incredibly Dumb that is going to take down a lot of nodes.

If you are betting that you can just add enough redundancy split brain can't happen, I have to question why I should take you seriously with important data.

(It also indicates to me this is going to be ludicrously expensive to set up though, but that's another issue)

Redundancy, quorum protocol, proactive testing, rigorous QA.

And actual 24x7 environments with important data are ludicrously expensive. I expect InfiniSQL to be less expensive since it's based on x86_64, Linux, is open source. But yeah, hardware and environment need to be right.

I'm not sure what I said wrong, but I'm nowhere claiming that split brain (or any failure scenario) can be ruled out entirely in all circumstances--but in practice, split brain is avoided 24x7 for years on end in many different architectures.

It's not magic.

Just like you can't have "enough" storage redundancy. You can have a 100-way mirror of hard drives that will still lose data if you lose 100 disks in less time than somebody replaces one of them.
