I disagree that there is no use for a policy at all. Sure, there are laws, but I would prefer not to have to use them - that we can avoid misbehavior in the first place. Having a good and consistent policy helps Wikipedians navigate. Don't (just) define what is forbidden, but (also) define what is 'good behavior'. For some people this is obvious, but there are also community members that find comfort in knowing what is a safe guideline to follow. There are also community members that will find comfort in knowing that they can expect certain behavior from their colleagues, no matter the country the event happens to be organized in.
I do agree however, that arbitrariness is not a good outcome. If there is even the impression that there is arbitrariness, the value of the policy is tainted. This is why I'm asking to review the policy - not because I disagree with the core principles, but because I don't like how it plays out - at the very least in the perception. But in this, I'm starting to repeat myself.
Best,
Lodewijk
