That’s all true, but people in Kanab and Southern Utah in general have lived in genteel poverty for decades now when reasonable development could have happened.
Recall that Robert Redford (”Bobby Bluenose”) was hung in effigy in Kanab back in 1975 for his opposition to the Kaiparowits plant. People there (including Navajos) saw it as a reasonable job generator; it would have had state of the art scrubbers for reduced pollution.
There’s no reason sensible use of the land can’t include protection for real scenic beauty and artifacts along with managed development.
