Yeah, there are a relative handful of places in the US/North America that, during remotely popular times, access has to be rationed for good reasons. The Enchantments are definitely one of those--I'm resigned to never be organized/lucky enough to go there (and that's not even a national park). And once you're going to ration, it's just a question of how: very high fees, lottery for applications within some window, first-come first-served x days in advance, queue at the ranger office on the morning of and hope you get lucky or have to go somewhere else...

Excessive fees going to a for-profit company is a separate matter but doesn't change the fact that, for any reasonable fee structure, way more people want to camp/stay/hike in certain places than those places can reasonably support.

Different approaches just have different drawbacks. In general, I'd probably disfavor technological sniping approaches for most sites in this day and age in favor of a lottery with a wider window. (And for most public properties just increasing pricing isn't really the right answer.)
