The last paragraph of the article is disappointing. That said, I do disagree with the concept of mandatory caddie or cart. I believe that walking is an integral part of the game, and golfers always should have the option of carrying their own bags or even using a pushcart (I still don't understand why pushcarts are acceptable inthe UK and Australia, but they are considered taboo here in the USA.) I think caddies are a luxury (one that, quite frankly, is above my paygrade, particularly at this point in my life).
If I'm playing PV or Merion, yeah I might want to experience the course with a caddie for the first time. But the choice should be mine. I think that Bandon has the correct model. Offer caddies to those who want to take them, but allow carrying and pushcarts as well.
My former club generally allowed carrying, but it was restricted for members over 35 (and guests were automatically charged a cart fee). On weekend mornings before 10:00, you could carry if you wanted, but if there were caddies available and you were 35 or older, you were charged a $10 trail fee. That policy really bothered me. As a member at an equity club, I think I should be able to decide whether to take a caddie or carry without being charged some arbitrary fee.
