Melvyn, you are differentiating between "true links golf" which I think is played on less than 200 courses in the world, and golf in general, which is also played in parkland, heathland and other non-links settings, on many thousands of courses. Trees are right at home on the vast majority of courses in the world. If planted and managed propoerly, they are a joy and an enhancement to the pleasure of the game.
It's like the old Beach Boys' song, "I Wish They All Could Be California Girls," but unfortunately they aren't!
