This isn't a legitimate argument. The probability of you being struck by lightning is greater than two drives in the same mirror in a 4 drive RAID10 dying before a rebuild completes.
The probability of getting struck by lightning is a lot less than being struck by a read error when rebuilding from the only remaining mirror when one drive failed and you've replaced it.
I challenge you to do an exhaustive search for anyone, at any time in history, who was managing the array properly, suffering such a two drive failure and losing a RAID10 array, 4 drives or greater. Note that controller failures with all drives on one controller don't count, as that failure mode will take down any array of any RAID level.
