I got to thinking about this some more.
It seems that the rule of etiquette about repairing ball marks was not enacted until the 1950s (Dark Ages!). I'm looking back through my Hutchinson, etc., to see if there's mention of it as a Golden Age practice. What if we did away with the practice as an artifact?
We could be done with our golf faster. If it takes 15 seconds to repair a ball mark – and longer if you do a Zen job – then over 18 holes you could save 5 minutes per round – more if you’re one of these gardeners who’s in the habit of repairing extra marks.
We could delight in more unfairness. Do we distort the spirit of the game by sanitizing the greens to the point where they’re true, but entirely dull and predictable? Is this what we’ve come to expect from watching TV golf? Is the fetish of true-rolling putts just another pernicious influence of the American emphasis on “fairness” and the card and pencil? If we stopped repairing ball marks entirely, creating random micro-hummocks, might this not lead to future generations of golfer not expecting such manicured conditions, being more accepting of bad luck and the (literal) rub of the green, and gaining a bit more enlightenment about the game?
