My own explanation of equivalence ...

... is much shorter and fits into one paragraph

Think of a full frame sensor behind a lens of certain focal length and aperture. Then crop the resulting image to the format of the "equivalent" systems sensor.

To stay with your original setup, think of a 35-100/2.8 lens on a FF sensor, crop to the size of a mFT sensor, watch equivalence reveal itself.

Covers everything but diffraction nicely. Add some more pixels and it also covers diffraction
