I would nitpick that the maximum amount you can deduct is set by the government, and thus somewhat arbitrary, and certainly not Morally Objective. However, it is objective to you, the individual, and thus makes a very good Schelling point, and you are finding it helpful, so excellent, good for you.
I also largely agree with your statement regarding taxes, and have nothing to add to it at this time.
