I'm at a loss to see how the regulators failing to enforce spins during training, or failing to ensure that instructors are up to muster can be described as 'nannying' - quite the opposite.
There's no law against finding yourself a good instructor and going out to do some spins now, any more than there was when you trained. It's up to the individual, and I recently organised some spin training for myself, albeit for fun rather than because I believed (or believe) it made me a safer pilot.
Effectively what you're describing is 'deregulation', not 'nannying'.
it's really a sad state of affairs when the average instructor is (apparently) so unskilled that you can't trust him
I agree that your average instructor is likely to be less current at spins these days, than your instructor was back in 19??, but the move against mandatory spin training came from US statistics showing that quite a lot of instructors weren't up to spinning safely either, even back in the day.
