I'm confused because Wix responded to a question of the form "Why is X illegal" with an answer of the form "X is illegal because Y", and you seemed to respond as if they had said "X should be illegal because Y".
I'm not sure if it was a good idea to point this out.
You're right. He didn't make the argument "X should be illegal because Y" but the fact that "X is illegal because Y" raises the question, at least to me, should it be so? Is it rational?
