If that would happen we cut off the heads of non Jews who would be caught stealing (or transgressing any of the Sheva Mitzvos and I am not sure you would need two eidim and hassrah for non Jews) we would publicly stone adulterers and Jews who may convert to other religions (besides perhaps for converting to Islam). I also believe that if someone got off on a technicality they could be locked in jail and fed barley until their stomachs bursted, I’m not really sure about this though maybe someone here can explain this concept. Teenagers caught having relationships with the opposite gender would be publicly flogged and whole bunch of other things of this nature would happen.
I’m not sure what you may call this but it’s definitely not Utopia.
