Why would that be so and would it save people in places without

I'm thinking about them. Surely I can take a GPL perl script and run it
through a compiler, even the undump trick, and distribute that compiled
form, as long as I comply with the source supply requirements of the GPL,
can't I?

Gimp can also save equivalent .xcf.bz2, which are not so large. Even if
so, largeness of the source relative to the binary isn't usually a major
consideration for licenses themselves. It's a practical use problem.

Yes, usually, maybe with a cookbook file or some script-fu
that does the transformation described, if they got the
source material under a Share-Alike licence.

Please can someone tell me how to obtain the layers again after they
have been merged?
I can modify ELF binaries, but that doesn't make them source code.

Most artists do not want to distribute their sources? So be it.
Most programmers today seem not to distribute their sources either.
It is not a good argument for accepting binaries as free software.

I'd agree that an encrypted format is probably not a
modifiable one.

Probably, yes, if they got them under a Share-Alike licence.

Please can someone tell me how to obtain the wavs again after they
have been mixed and encoded? Again, this seems like hex-editing
ELF binaries.

Again, I'd agree that a WMA-DRM is probably not a source.

I think that reasoning confuses two unrelated topics. It seems
like saying "I like pasta because the sky is blue."

Above, the XCF is clearly described as the source material
of the PNG, and the WAVs as source of the MP3/OGG/WMA, so
I think it's obvious that they do have sources.
Hope that explains,
