Well, the thing is, if you've got a whole bunch of biodiversity and you cut down a small patch in the middle of it, where you grow your monoculture and use your big machines and whatnot, that's when this fuck-biodiversity approach is rather profitable.

But if you scale that up, if a whole bunch of farmers kill biodiversity in the same region, this will obliterate profitability. You need biodiversity for:

pollination
enriching the soil (we have no industrial process for creating humus; it's mostly just earthworms doing their thing)
pest control (birds and whatnot can eat your pests, if they settle nearby; they won't settle nearby, if there's no food for half the year because you've killed everything else)
resilience against pests and climate variations (if your harvest consists out of multiple different plants, then some of them failing from pests or droughts etc. is much less of a problem)

I'm probably forgetting more aspects, and we probably don't yet know all aspects either. But ultimately, plants have evolved to exist in rich biodiversity. It isn't just some moral thing to do, to keep that intact. Plants will falter without biodiversity, no matter how much fertilizer and pesticide you pour onto them.
