Having natural spaces within communities is vital for mental health. For example, Central Park in NYC is a vital resource for the city allowing people to enjoy nature close to home. Kids need places to go and play. Adults need space to recreate. Pets need space too. Why would you want to have no green spaces within your community?
Central park is way more wild than a playground, which is way more wild than a city street corner.
The Yosemite National Park front country is way more wild than Central Park.
The federally-protected wilderness areas, where it is illegal to use a chainsaw for trail management as that is not sufficiently wild, in the Sierra Nevadas are even more wild, but still have a ton of people, trails etc.
The Brooks Range in Alaska is yet even more wild - no/few trails, take a bush plane in/out, etc.
Allowing a bit more wilderness is always a utility - it doesn't have to be binary wild/not wild (and very little land habitable by humans has ever not been severely influenced by humans)
It's farm land. Sounds pretty wild to me. Also, we have wild land set up as parks as in national/state parks. A park doesn't have to mean slides/swings and a bunch of ankle biters running around.
Because people want/need accessible parks? Texas in particular has relatively very little parkland compared to its size, and its population-to-park ratio is getting increasingly out of whack
It just depends on the size. I know of several 1000+ acre parks that would be essentially considered wild areas with the exception of a few hiking paths.
They are full of wildlife ranging from small rodents to bears.
