Yup, for Yellowstone, that’s 3 entrances, so three sets of booths. It’s largely to cut down on traffic (traffic gets really bad as-is) and maintain the infrastructure.
The only reason you’d go to any of the entrances is to visit the park, there are no through roads or anything, and it’s like an hour or two from the major highways, and several hours from a city larger than 10k people (aside from the tourism towns just outside the park). And the traffic to get into the park is backed up for an hour in the morning for people looking to get lucky with extra passes (there’s a maximum capacity).

Yellowstone has limited access by road, but you could hike into it.
The Grand Canyon has visitor’s centers and a few established areas with infrastructure for various activities, but you could hike to it, but getting into the canyon is another matter.
