In any case, I think "detail per frame" is more important than "detail per unit area" in practice (I think that's what you're comparing above; Acros apparently costs twice as much per unit area in 4x5 as in MF, right?). One of the points of shooting large format is precisely to enlarge less, i.e., to put more film area in the image; of course that costs more per frame, and of course it doesn't make the underlying resolution of the film any higher, but it does deliver more film resolution to the viewer.
In short: It's not that you double your cost (per unit area) to keep the same resolution, it's that you sextuple your cost to triple your resolution. Diminishing returns to be sure, but somewhat offset if, like many of us, you get a higher fraction of keepers in LF.
Yeah, I'd agree with all that, except that I'm not sure technophilia is necessarily something to "recover" from. Complicated toys are fun; they're not the only thing in the world, to be sure, but they're fun. And I think some of us actually like the challenge of using nominally inappropriate toys, just out of cussedness. I know I do.I'm also a recovering technophile so I enjoy the challenge of using (and getting the most out of) complex toys and while that's a bad reason to choose a particular artistic approach/technology, I'm pretty sure it applies to a lot of LF users. It probably doesn't matter though as long as the technology isn't actively holding you back - I make a point of using more-appropriate toys when taking more-spontaneous photos like candid portraits in poor light, or travelling around the world.
