I agree that forests are an economic resource and would argue that a fire, caused by humans and exacerbated by human forest management, is a devastating outcome economically. These aren’t wildfires that are merely periodically clearing the forest floor allowing for better forest propagation, they’re burning hot enough to kill everything - trees, soil, and anything in between. Along many parts of the Pacific Crest Trail in Northern California, you can see aspects of slopes that have been burned at various times over decades and see that those forests burned are struggling to come back. I hiked the entirety of the Pacific Crest Trail this past summer and would argue that I have a decent sense of the status quo of the scope and qualities of the devastation of forest fire in those forests affected by those fires I’ve cited.

What difference does it make?

1. These aren’t forest regenerating/undergrowth clearing events - they’re apocalyptic in their devastation. A million acres unnecessarily burned in the Dixie Fire.

2. Forests are limited, threatened resources. Muir wrote a passage calling the sheep herd he was tending in his first summer in his beloved Sierra “hooved locusts” but managed to rationalize the devastation wrought by those sheep immediately after by reasoning that there still remain thousands of untouched high Sierra meadows. Just as there aren’t a thousand Tuolumne Meadows, there aren’t a thousand Lassen or Plumas National Forests. Every single one is irreplaceable on a timeframe that takes into account forest regeneration and the scale of these fires.

3. Paradise, CA. was completely devastated by the Camp Fire - the deadliest and most destructive fire in California history - and started by poorly maintained PG&E power infrastructure. Lahaina, Hawaii was utterly devastated in a similar fashion by a fire with a similar causes Even ignoring that our forests are being irrevocably destroyed, human caused forest fires are engulfing and destroying entire communities, killing people unable to evacuate ahead of wind driven firestorms.

4. Besides forest health, threat to life and property, here’s one that I’d actually expect to land: the threat posed by increasingly powerful fires started by humans and exacerbated by human activity (including the forest management you cited) driven by increasingly extreme weather conditions and events is going to make home insurance untenable. People are already being widely priced out of insurance markets whose actuaries are now pricing in risks that include potential for outcomes like every single home in Lahaina/Paradise/Malibu/Santa Monica is devastated.

What does it matter? Well, even handwaving away the devastation wrought on our forests by man made fire, those fires that affect you and your home insurance bill are essentially that complete set of fires that aren’t naturally occurring events. You don’t have to take my word for it - an actuary will have you understanding it sooner or later.
