I'm not sure what the specifics are regarding the practice of conceding putts.  First, and foremost, it is a reflection of the nexus of the game as a sport of gentlemen (and ladies).  It is a crucial component of non-competitive golf now, and the practice helps avoid six hour rounds.  Even in charitable tournaments, which are truly just for fun, when the event forces players to putt out there are players who will try to emulate their favorite tour pro's pre-putt routine even for a six-inch tap in.

I've gone through two periods of struggles with Y*PS over the years.  In both of those, my friends began to concede putts just to avoid the extreme discomfort of watching me struggle.
