There are two very distinct statements which say entirely different things: "markets are probably not efficient" is a fine statement and I agree with it easily.

"Markets are provably not efficient because xyz" is much harder to agree with, especially given that paper, since it's the same as saying you've actually proven that P!=NP and thus requires an extraordinary proof.

You're claiming to have a solid proof. Just because someone agrees that your result is likely correct, that doesn't mean they agree with your proof.
