Because you went out of your way to prevent it! TagBox is not a number (of any kind), so applying N to it doesn't give a Real. In twelve of years of using Mathematica, I have never used TagBox, FractionBox, or PolynomialForm, and your example doesn't tempt me to start. I see no need for such oddities, especially those, like PolynomialForm, which are undocumented.
