Why? There are always factors that are out of your control. Minimizing impact of those factors, having contingencies and expediently adapting when things don't go exactly as planned is pretty much what good planning means.
The kinds of things RPG adventurers get into almost always include some situations where there's limited contingency planning possible (because some information not accessible in any functional way and functional continengicies require the GM to be very much on the same page as the player). Using the standard you're working under almost always trains people that the simplest thing is to go directly to surprise and violence and skip anything else.
