Artists have been waxing philosophical on this for ages: when does a painter know when to stop, put the brush down, and call it good? The sooner you can do that, the sooner you can move on to the next thing. How good is good enough?
True, music isn't static like a painting, but from a compositional pov, it's the same thing. NP was known for his compositions and obviously enjoyed that. And why not? Everyone else already varies the drum parts from performance to performance, so front-loading the creative effort and casting it in stone seems like a pretty good idea, actually. If nothing else, it was novel.
You could also turn around and say that anyone not taking the time to dial it in and nail it down before hitting the record button is just lazy. I wouldn't make that argument personally, but I will admit that what I lay down in the studio usually is what I do from then on out, at least for the bits that I felt worked particularly well.
Also, instead of pointing out everything he is not (or anyone for that matter), acknowledge what he is, or has brought to the table, and allow yourself to either be impressed by that, or not.
I was never impressed with Buddy's funk or Neil's jazz, but hats off to them for stepping outside of their comfort zones. Their respective "shortcomings" in those areas does absolutely nothing to minimize or negate what they were great at.
