I think your criticism of Graeber is somewhat fair. And it's a fair point that incorrect popular/lay theories don't mean experts don't know how things actually work.
That said, I do think Graeber is right to emphasize the role of culture and belief--anthropological ideas--as an antidote to overly quantitative/mechanistic models. I'm not an economist, but it does seem like behavioral economics was pretty revolutionary in advancing the idea that humans are not just rational utility maximizers, despite Keynes using the term "animal spirits" nearly 100 years ago.
Again, speaking as a layperson, it's frankly a bit weird to me how distant economics, anthropology, and psychology seem to be from each other.

This is a false and misguided dichotomy. Nothing prevents you from taking culture and beliefs into account when you create a model.
"Just-so stories that support their preferred ideas" + "so nothing prevents you from taking culture and beliefs into account when you create a model."
A litte OT but,... years ago i read a HN-Topic, about um 'What to change if we could'. I read some postings, where people seem realy angry with abuse, misuse and malpractice, done by people who may or even may not wanted to be remembered as: 'This is our work, we do this cos we are in empowered to do so' (won't explain it more, back to more context:)
My conclusion by that time was, questioning: 'Is privatizing favourable?' Cos there is confusing data, complex situations and a need for easy hypotheses...(and solutions maybe) The assumption that time was, that the gov spend a (huge) budged to pacify many more conflicting 'partys' than a private entity would like to do/or will, cos generating income through excessive spending (may 'only work when'/'need expotential growth') means nothing more than the need to reinvest profits to bigup the businesses.

And now really OT, I remember some of the friends around Putin are building contractors, and the TV-shows about the war in Ukraine or Syria before um...
Behavioral economics, the bastard child of psychology, is built on an edifice of fashionable nonsense. The field is rife with grand generalizations based on dubious conclusions from small under-powered behavioral experiments. Just look at what a disaster the much hyped priming studies turned out to be. I would not count on behavioral economics to advance a more accurate understanding of the human condition.
I know very little about economics but I am compelled to point out the irony in your comment.
How I understood your comment:
"This whole field, consisting up of many people trying to do understand things, is just a bunch of nonsense generalizations."
Frictionless spheres are fine in Physics 101 and Homo economicus is fine in Economics 101. Like all models, economic models too are wrong but some of them are useful. The bulk of economics after 101 is about how the models break.
The idea that humans are not perfectly rational self-interested actors has been part of mainstream economics at least since Keynes.
Is it the whole story? Probably not. Like I said, I'm not an economist.
But given the extreme challenges in empirically testing macroeconomic models, it should be no surprise that economists might--as somewhat irrational humans--over-rely on theoretical models.
