What sort of emergency do you have in mind?
Example 1: medevac.
Example 2: You live up north, it’s winter, and your house’s heating just died. If you don’t fix it by the time the house cools down to below freezing, some of your water pipes will burst.
Maybe you could drain all your pipes in the latter case. But I imagine there are other emergencies, of course.
