My point is that whether a force does work doesn't depend on what the force is. It makes no more sense to say that magnetic forces do no work than it does to say that gravitational forces do no work.

But magnetic force does no work to a charged particle in any way. While gravitational force CAN do work and it does work on most cases(every non circular orbits or just a mass falling down). That's why magnetic force case is emphasised.

But on your take about magnets, its not the magnetic force that do the work but the associated electric force

I suspect I'm using a naive macro model and inaccurate terminology whereas you're using a micro model and accurate terminology.

Is there even such a thing as magnetic force? Reading up a bit, it only talks about magnetic fields.
