He didn't say it was useful image data  :-)

A 4000 dpi scan of a 35mm frame, at only 24 bits/pixel, is 60MB.
So is a 2700 dpi scan at greater pixel depths (from scanners that
can deliver 10, 12, or 14 bits per component).

A good lens can easily deliver 4000dpi of resolvable data on modern
100-speed films (although that's getting pretty close to the usable
limit, especially for hand-held shots).

Claiming a cheap disposable camera can do that well is hyperbole.
