This administration fired thousands of Forrest Service and BLM employees at the start of the administration last year. Those workers were the ones that were responsible for the maintenance of these lands and for the fire lookout programs.
Maybe they couldn't have prevented this fire, but it's pretty clear these fires are much worse today because of those firings last year.
In general externalization of costs prevents/hinders development of competing approaches to increase efficiency and related tech development, and as we see the cattle ranching and beef production is still done like 2000 years ago.
If you think ranching hasn't changed in 2000 years you know nothing about it. First, what we see in Canada & the US is most similar to Spanish open grazing of ~200 years ago, not some sort of neolithic practice from several thousand years ago. Then the obvious and game changer was barbed wire, and now intensive industrialization such as feed lots, genetic selection & artificial insemination, GPS tracking and data-based herd management. Public grazing is such a minor part of the picture now. The technology you call for is IMO the worst development: factory meat and massive consolidation.
