Don't apply physics to One Piece. Just accept what happens and be happy when things are explained in the manga. It's best not to ask questions. Even if your friction idea were somehow plausible, the water pressure and temperature would nullify it. As for your haki idea, no. Friction does not lead to density. The better you control your haki, the denser it can become, and the more of it you can imbue something with. And magic? Really? You try so hard to make something plausible only to resort to the most vague and least likely explanation ever? Treat yourself better than that.
