But why is it human nature to put a bench right where people are walking. It's like people in charge get off on creating obstacles for the common man just to feel powerful.
Well, don't design park the brain-dead way and try to actually think about visitors and their needs. As in make a straight route to a damn crosswalk instead of making it an obstacle course.
Ackchyually, grass is almost always a mixture of different species (ryegrass, fescue and bluegrass) and therefore not a monoculture.
A lawn has its uses in parks, for example to have a Picknick.
If you trow in some clover, daisies and ribwort, don't spray and patches are left to grow to provide shelter it's not that bad for biodiversity, depending on the climate of course.
Yeah, there's grass and then there's grass. Sure. I got no beef with a field of mixed grass that's left to grow, especially if there's mixed native wildflowers etc.
It's the fields of monoculture non-native grass that the Suburban White Dude[tm] wants to obsessively cultivate and that seems to be the goal of parks departments everywhere that's the problem.
My partner ranted to me the other day that she couldn't get a 10m^2 area from a local municipal parks department recently for a Miyawaki forest plot. No reasons, just "no." Very frustrating group of fuckin' boomers.
The park design should have accounted for the crosswalk on the top intersection from the get go or, alternatively, once the people made their desire for a path there obvious. The park isn't some sentient thing with its own opinion, it got made by people with 2 main functions: enhancing the environment and serving as a foot path. It is obviously failing at the second until the designers finally relented and put a proper path down to the crosswalk.
Note: you will always get people not using the path but when it's enough people to form a permanent trail then the park design obviously did not account for a rather popular destination and should be revised.
