Beagle,
If or when you fail your JAR Class 2 medical and wish to continue to fly, you will be glad of the NPPL (in future for Annex II aircraft) and the future LPL (for Annex I aircraft). Talk to the thousands who have done so already. Also to the many pilots who do not need a JAR PPL and all the clap that goes with it for basic VFR flying.
For generations the world of private flying has been held back by the inherited thinking of pre WW2 days when it was a 'privilege' (in more than one sense) to fly and the authorities granted you the privilege. They also screened out supposed higher risk candidates by means of applying high medical standards because of the investment being made by CAT and Military organisations in training pilots. The screening should be more appropriate and proportionate to risk for lesser mortals than ATPLs or military pilots. Look at the empirical evidence in other fields. It is compelling.
We must break the assumed link (by the former JAA) between JAR PPL and higher licences. A PPL or LPL should be capable of being seen and accepted as an end in their own right. And with the ability to progress training and experience from LPL to PPL to CPl etc with crediting.
You and others need to recognise that we are trying to reduce the barriers to entry / barriers to continuing flying, based on objective and proportionte risk principles. Otherwise the elite breed will die off gradually without successors from the young taking over the mantle of private flying.
From Cologne where we continue the battle......
Good day
