I prefer to walk, but spend a lot of time in carts. My most played course is a pain to walk, but it's close by and we can get out almost any time, even if that means driving out to hole 13 or 4 or something.
I can play faster on cart-path-only days than I can walking. I can play 18 holes, in a twosome, in two hours in a cart allowed to go anywhere, and that takes about 2:30 when walking (I've done it in 2:15, but that's at a really old course with very close greens and tees, and no lost balls, etc.).
I appreciate that cart paths and carts are "bad" for golf. They're expensive, and unsightly, and cause damage. I also appreciate that without cart revenue, many courses would likely be closed.
If you enjoy golf, good for you. I don't care how you enjoy it. If you want to roll your ball in the fairway, give yourself four footers, and ride in a cart… so be it! At least you're enjoying the game I love! Who am I to judge you for riding in a cart?
My friend José, who has since passed away, had to play in a cart, and even play executive courses in a cart, but otherwise looked fine. He had a heart condition that ultimately took his life after his second heart transplant, but I introduced him to golf and he could only play in a cart. It's sad to think that someone in another fairway might have been judging an otherwise healthy looking 26-year-old guy for riding in a cart, even while playing the 4300 yard executive course we'd play from time to time.
So long as people are good to the course, and good to each other, why does anyone care if they're in a cart or not?
P.S. I love taking a caddie, too, but man… I'd play a LOT less golf if I had to shell out an extra $100 every time I played.
