This a silly analogy, and bears no resemblance to the actual appearance,
which is quite nice in my opinion.

... and yet, it simply _doesn't matter_, because highlighted regions are
_temporary_.  I use Emacs too, and I find the behavior very reasonable.

Font-Locking is nice, but it's very much secondary information, and
suppressing some of it when selecting a region (when your attention is
focused on the region), is just not a big deal -- indeed, I didn't even
_notice_ that font-locking colors were suppressed by the region on a tty
until you mentioned it!

Yes, because hi-lock uses the background.  This is probably not
particularly important.

... which is quite irrelevant, since your "foghorn" analogy is not
accurate; arguing by means of poor analogies is not useful.

All of your buffers have activated  regions when Emacs starts?

If so, _that_ sounds like a bug (so please try to send a test case);
needless to say, I think, I do not see this behavior.

Of course not, since as far as I can see, there isn't actually any

It seems pretty obvious to me that all of this is much more a matter of
taste than anything else.  You have made your opinion on the matter very
clear, repeatedly.  The Emacs maintainers have made their best judgement
as to what the majority of Emacs users will prefer.  You know how to
turn off the highlighting.
