If you are dealing with really high security stuff where you'd rather burn your data than have any risk at all of it being compromised, then I could see this making sense. But nearly everyone needs access more than they need security. This feels like putting yourself at risk of at least issues if not crisis to protect against something less likely to happen.
Nearly everyone I know has lost a phone at some point (broken to some degree.) Or just had a phone die on them. I know almost no one who has had major systems hacked. Both happen often, but one is, I feel, many times more common.
