Good post 4x4
There has never been any kind of safety case for an anti N-reg action, and not even EASA pretends there is any such.
The justification given by the EASA gravy train riders, when asked face to face, tends to be "we are Europeans and we must have European rules, not American rules".
That kind of reply is self evidently stupid but they are in power whereas you are not
It's like you telling your 2 year old kid that he can't have the ice cream because Mum did not let you buy the car you wanted. It works because you have all the power and he has none, but it leaves the same kind of bad taste in the mouth.
Regulators aside, the people who are in favour of these Euro rules are usually doing it for straight financial reasons.
Maintenance shops like N-regs because they charge the G-reg price but they don't have to change (Part 91 ops) some lifed parts and they get you to pay the A&P/IA separately to get the Annual signed off
