I agree from philosophic point of view. 

The idea behind was to make somebody who wants to ZAP the program life as
hard as possible.
If someone is able to ZAP a program I assume he is in most cases able to
write it.

I use another method too to ensure, that the program runs unmodified. But
two traps would be better than one - was my idea.
