I'm really not sure how, "I don't like the rules that benefit you and harm no one, and I will make sure you don't follow them either" is a "moral" position.
...aah, but it does cause harm, Mark. Otherwise, I wouldn't be caring a whit about this particular abberation of time logging regulations.
The harm is in the guy who gets a Private with a minimum of 5 solo hours going around a triangle of 3 airports of which only one is 50 miles away.
Now he rides 50 hours in his Uncle's Piper Mirage (ASEL) while it's on autopilot and GPS and logs 50 hrs PIC X/C. Worse yet, his Uncle is a sorry flight instructor and endorses him for complex/HP so he can log PIC in the Piper Mirage, even though his uncle would never let him even taxi, much less fly, his airplane solo. And the guy wouldn't want to. He knows he isn't qualified, he only wants to fill the blocks with "regulatory required" time.
Why does the FAA require PIC time? To show time that the person acted as PIC.
This guy is not getting the experience that the PIC hours are supposed to reflect.
Admittedly, this is a very small number of cases. With most everybody, the difference between 'earned' PIC time, and 'logged-when-not-capable' PIC time would be negligible, but in some cases, such as I have described, the instructor is responsible to insure the student is not logging PIC time when he is incapable of performing the flight, proficiency-wise.
..and it is all legal. I'm not bending the rules, I am using them as intended to log approprate PIC time, as sole manipulator.
The typical Private Pilot going for an IR in a 172 is going to log all the time as PIC - he should. Unless his instructor does an unusual amount of demonstrating approaches.
But a private pilot who took 100 hours to get to private - because he is slow -who rides along in a machine in which he is essentially a passenger, and 'maneuvers' himself into positions of logging legal time without the experience it is supposed to represent in certification, and he eventually gets a commercial certificate - well, do you want your daughter to fly with him?
The flight instructor has a responsibility to insure any flight he signs off on represents precisely what happened. If the student was not sole manipulator, the instructor is falsifying and signing a legal document if he allows the student to log PIC.
...and I believe the FAA will agree that the instructor is the one who determines 'sole manipulator', not the student.
