As soon as the User does some little tiny editing we no longer can
discern reliably between invented bits and important bits.

The whole point we're trying to make and which you refuse to understand
is, that "they already agreed to and want" only applies for images they
created themselves from scratch. It breaks down immediately when they're
working with images from other sources, like the clueless marketing
droid sending you a jpeg logo file.

Here the user does *not* do a concious descision towards a lossy file
format. He did *not* agree to loose bits on saving even when he opened a
JPEG. This whole "user indicates his intent by the file format he opens"
just breaks down when working with images from other sources.
