The air, much like anything else, can be pushed in a hypothetical frictionless environment.
Edit: Is not a proposal, it's a fact. How does a desk fan propel air into your face? (solid vs gas). How you could not answer this question yourself is frightening.
It's appalling that you'd try to mislead others and shame them for their alleged lack of knowledge, only to then spout this kind of nonsense.
