The most hilarious part about these trolls is that they argue from a retroactive point of view. Laws are never retroactive. According to TPTB's "expert lawyer opinion" pokemon cards were really a security because they appreciated in value due to demand after they were sold as a card game. Genius.
Well, he is not an expert and has the right to be wrong. Of course, noone seriously believes that TPTB is better than Ethereum lawyers but if one conforms to TPTB's rules then the one conforms to all possible jurisdictions. So TPTB's opinion is useful to some degree.
He has the right to be wrong, but he does not admit that he's wrong. He states things as a matter of fact and thus deserves to be ridiculed for it.
