Yes, it's madness. The whole thing is pointless even if it did work, which it won't, because as I posted above people will ignore the rules almost instantaneously, especially once they're a few pints in.
I'll just end this by saying that some people are like you, some people are like me.
We're not going to stay in fear forever. You might. I hope whatever happens that you manage to find peace with it. Godspeed.
