In a Capitalist economic system money is the only metric. That's why, even today, cities have to fight to get money for upkeep of parks and greenways that are packed with people using them. Don't be too hard on the good ol' USA; countries everywhere, as soon as they acquire discretionary income, become hell bent on following in our footsteps. That's why their complaints about us ring so hollow.
But back to "Moonrise". Artists should always challenge sacred cows. The truly sacred cows won't mind because, being truly sacred, they're worthy of and not at all diminished by the attention. (I'm talking a secular sanctity here, a cultural one. It'll keep tempers under control.) There should be a Monthly Shooting Assignment where the subject is the Moonrise. Your own. Copy, parody, send up, slavish duplication, whatever. As long as it's all yours.
Every time Adams told the story it became more dramatic. Now, that empty highway where he scrubbed to a stop in the 1940s, and where I stood in the early 2000s when it had been reduced to a crumbling frontage road, is gone, used up in a widening of the highway. Eventually there will be modular homes on the land between the church and 285 and the view, and Adams's image, will be gone for good, leaving only the eternal moon and the eternal dead. Which might have been what he was getting at all along, even if he didn't know it at the moment he released the shutter. But I'd bet he did.
