Excellent Meditation!

Let me start out by saying I admire your drive to get 100%, it is not an easy thing to do. Personally I think that 100% is (in most cases) overrated, and >95% is acceptable in most cases, but you make a good argument.

Of the things you said, I think this:

even if everything is tested, it might still be wrong
and this:
fixing the remaining bugs as they arise is made ridiculously easy in most cases, because it is so well tested. Fixes that break existing behaviour are highlighted as test failures - without test cases you might never know
are two of the most important points.

Test/Code coverage is no silver bullet, as the How to Misuse Code Coverage article pointed out. But as your next point says, it is sure nice to have those tests when you are fixing bugs.

Again, excellent post :)
