You're not the one making the decision but are "preparing" for a scenario that may not ever occur?
Then I suggest you prepare for: the stoplight that may malfunction on your way to work, the number of parts in your rig, or the bus, or the train that you take to work that may fail and the number of possible tweakers who may rob you in any number of ways. That's just on your way to work.
The oven at home when you're not there, the front door lock parts that may be faulty and exploitable by a smart burglar, etc, etc. All of more direct consequence to you personally than the guy in charge.
I'm failing to see how thinking about it now applies perfectly to a future hypothetical situation. If it happens in the future, conditions will have changed, probably the solution, too.
It's a matter of using one's time wisely. Speaking of, I'm prob wasting mine. Gotta go.
