Good comments so far, even if I feel differently.
Par does one thing for me; it sets the points during a match in which handicap strokes are distributed. Otherwise, I look at it this way:
My 75 beats your 80
or
You won the match 5 and 4
I feel no reward in taking x number of strokes on a hole based on someone else's idea of what a standard is. No, that's not completely true, as I revel in making an "eagle" just like everyone else. But, at the end of the round, it's either about beating an opponent by x number of strokes (and making a 3 on any hole is a good start) or winning x number of holes more than your opponent before the round ends. If I make a 3 on a long hole, I will still feel the elation of an accomplishment that, for my skill level, isn't ordinary. The number of par doesn't create that, it comes from within, IMO.
The older I get, and the more I learn about architecture(and, consequently, how I interact with it), the more I value fun golf shots vs. an arbitrary concept, such as par. If my bogey beats your double bogey, and we both had fun, then what do I care about the relationship of our scores to par?
