What if I want to distribute only one chapter of the book? If there
are 3 invariant sections, then it might well be that the invariant
sections are three quarters of the whole. Is it still considered
secondary? Or may not just distribute one chapter only?

I can tell the same about software: Many users get windows with their
PC. Since they aren't programmers, it doesn't hurt that they can't
modify it. The question is: Does windows do what they want?

Yes, and you add your own invariant section. And the persons which
gets your new book also changes stuff and add their own little
invariant section. Then somebody translates your book in another
language, and adds their own invariant section in their language to
the invariant section in your language (because they may not translate
invariant section). And then we're about 20 years later, but we have
still have the first invariant section which has actually no relevance
anymore and even isn't in the same language the main book is.

Huh? I don't follow this. A section not having anything to do with the
main part describes how the main part was meant?!?
