Human Factor,
What a load of crap !
Point and power works perfectly well on any fixed wing aircraft.
If you are having to raise the nose so much that you require full power then you can only be far too low in the first place. Your circuits must be absolutely massive !
All Military and Airline pilots use point and power and it is simply rubbish to say it does not work on light aircraft. Previous comments have already stated that you will have to use it for instrument work and to the best of my knowledge some light aircraft can do instrument approaches as well !!!
On the subject of flap I can assure you the CAA want people to use full flap landings ALL THE TIME.
The reason airlines sometimes do not is because they have detailed performance available for every runway and any flap configuration they may want.
Light aircraft DO NOT and to be honest, performance can be a bit of a dark art with a bit of guess work involved.
Your aircraft manufacturer has spent a lot of time developing and producing your full flap so that your aircraft lands in the shortest distance possible. The full flap or drag flap is produced to counteract ground effect which otherwise would enable your aircraft to fly that bit further.
Detailed surveys have been carried out in the states looking at over 2000 landings at one particular airport. Of the incidents that occured, every one of them was with aircraft using reduced flap. Not one using full flap.
