So where is the Physical, as distinct from the Chemical? Are biologists foolish to study that arbitrary abstraction biology? All sciences abstract and they all blur with other disciplines.

If it's a historical object that makes something fall short of a science, biology, geology and astronomy fall short. It sounds like by 'psuedoscience' you mean 'social science'. There's a large literature on the distinction between social and natural sciences. They are different enough for various reasons (especially the reflexivity of the discipline on the object of study and the creativity of human actors) that you might want a new word. On the other hand, you still might want to distinguish between good and bad social inquiry in a way that raises the question of method, so you would end up with a replacement word to distinguish social science from social psudoscience.
