Alternatively to be cheap, you could begin with the question, but with the inequality the wrong way around. Then obtain a contradiction.

Its more ugly mathematics than cheap. "Fake" proofs by contradiction aren't pretty.

How is it not proving anything? Showing that LHS-RHS is non-negative or non-positive is precisely a proof of the claim the quesiton makes. You are not making any unjustified assumptions.

I guess if you put it that way....then yes, it is a "proof".
