I wouldn't think that would be the only reason to state that something matters or doesn't matter. If they raise your taxes to be 120% of your net worth, the sun will still rise tomorrow. Would that mean it didn't matter that they raised your taxes that high?
But you decide based on your own criteria. I'll get back to some of the other questions in your post in a sec.
Matters to who? Me personally? Or the Universe at large? The Universe, and any Gods who might exist, is like the Ultimate Honey Badger. It don't care.
