I don't think your attempt to show a difference between that and software makes your point.
The bulk of software project costs is labor. And there are certainly a lot of business folks who say "ok, the bulk of the cost is labor, so labor is a commodity, so I should be able to hire any programmer to do any type of software" and hire cheap devs and see things go sideways if they don't stick to fairly simple, rote, lowest-common-denominator technologies that are much closer to 90s-style-PHP than they are to "the latest Python or Javascript."
If you've spent your whole career in coastal California startups or FANG you may never have seen these people at all, they don't really live in the same job posting/hiring/skill set universe. But it strikes me as very similar to "labor is the most expensive part, concrete vs lumber isn't gonna be that different in parts, so I should be able to pay the same for labor for the unusual things."
