It also primarily untouched. Contrast that with a public park in a city, where there are actually people.
Unless there is staff to keep the park clean, it isn’t long before it’s trashed. Same with beaches. Look no further than the “adopt a hwy” or “keep xyz city beautiful” programs and the literal mounds of trash they pick up. There’s always a handful of people that care among a vast sea of those who don’t give a shit.
That doesn’t really compare with a handful of ranching families that collectively maintain 100’s of acres federal lands to graze their cattle.
