For some of the things the author complains about there really are no good options. You can only shove so many people up the Half Dome cables on any given day or so many campsites in Yosemite Valley before it becomes a nightmare. You can't just build more of the experiences people are looking for in national parks like you can build taller buildings in a city. So your options are to ration by price (which NPS/etc generally don't do), to ration by luck (lotteries for e.g. Half Dome), or to ration by ability to plan ahead (far-in-advance reservations for campgrounds). None of these are great but what is the alternative?
