The problem here is that you are all applying sense to the situation. Of course YOU would carry a plb at the appropriate time. Most of you already do; there is no need for the legislation.
However, put yourself in the chair of the regulator........
This rule is probably being introduced because, in some countries, people can't be trusted to be sensible. A blanket requirement ensures compliance..... Only those diehard idiots being targeted will still not carry one!
When I left the military, I always felt naked flying without a PLB, even for circuits......
