I did not claim that the paper contained any mistakes. Rigorous proofs do much more than simply eliminate the possibility of mistakes (though they do that too); they make the argument accessible to a wider mathematically literate audience who may not be familiar with techniques which are standard in the author's field. I know a not-inconsiderable amount of graduate-level probability and a bit of stat phys and yet still this paper is not a trivial read. I'm sure if I stared at it for a day I could figure out the entire argument, but the point is I don't have a whole day. Theorems and Lemmas are a protocol for mathematicians to communicate efficiently. Considering the level of offense you have summoned up, I assume you must be in some mathematical field, so I am surprised you do not appreciate this.
