Yes, I missed it, albeit not completely. ;-)
Your essay serves two purposes: 1. to support some of your ideas and
2. to represent your way of thinking up to the smallest details. The
invariant sections are the way for you to ensure that both 1. and
2. will be satisfied all the time (albeit not in the best possible
way). It would not be possible to protect 2. if the license permited
modifications of your essay.

Yes, you are right -- I am not allowed to improve 1. in a ways that
would invalidate 2. If you think that 2. is not important for you,
then in the copyright notice you can give to the users additional
permission to modify your essay under certain conditions.

The text of GFDL says that you have to "preserve all the Invariant
Sections of the Document, unaltered in their text and in their
titles". This means you are allowed to use footnotes - the text will
still be unaltered. Very often the publishers are adding footnotes
without permission to modify the author's text. In translated texts
the footnotes are even more often (again without explicit permission
from the authors).

I see. I can answer that there are other ways to achieve the seeking
result but I must admit that if you don't give me explicit permission
to modify your section the result will not be the best possible.

It makes impossible to adapt your code to another programming
language. However ... [read below]

This probably means that the final result of your code has to be
executable binary. However:
Suppose your license contains the following rule:
If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive
use in the most ordinary way, to print or display the following
text: YOUR TEXT FOLLOWS HERE.
Notice that this requirement is very similar to section 2c of GPL. Do
we consider such a license free?
My personal opinion is that this depends of what exactly the license
requires to be printed. However I am unable to give any precise
