1) central bank loss of independence is one of the hallmark of failed central banks. I hardly think it's reasonable to think that all central banks are dysfunctional in such a way: while these institutions can and do break down, they are not designed to break down in this way. You're free to argue whether a given central bank is or is not sufficiently independent, but that's a more specific problem than the over-generalization made here.
2) it's not an exception to the rule at all. The rule for inflation doesn't mention how much money exists, it only mentions how much money circulates. More money existing does not necessarily mean more money circulating (eg.: money tends to concentrate in certain places for various reasons, rather than diffusing freely).
3) Sure, but two things that have similar features are not always similar in essence or nature. Swords and needles are both sharp, but you wouldn't argue that they're essentially the same. In fact in your own example, taxation for certain purposes could be either inflationary or deflationary (eg.: austerity measures, including those that involve taxation, are deflationary by design).
