Please don't add noise to the discussion by nitpicking something that doesn't need to be nitpicked. Shinkei already put scare quotes around the word "punished" so any reasonable person should interpret that he does not mean "punish" in a formalized legal sense. His usage was a figure-of-speech and not citing any legal doctrine. People can use punish the same way people can use reward when then say they felt "rewarded…
I think you're being a bit too harsh on couchand. First of all, I didn't interpret his comment as attacking Shinkei. I think he posed it as a general question for the audience. Secondly, I don't see it as nitpicking. It's a reasonable discussion to have. Piketty himself spends a fair amount of pages discussing how a global wealth tax might be implemented, and people's attitudes towards taxation in general have to be…
I'm not saying he attacked Shinkei. couchand criticized the message and not the messenger which is certainly acceptable. I'm pointing out that he's criticizing a figure-of-speech by stating to us the legal literal definition of "punish".

It's as if someone says "butterflies in my stomach" and a nitpicker adds a ST-MrSpock/ST:TNG-Data type of literal reply. Mr Spock asks, "Why do people use the term 'butterflies'? Caterpillars cannot incubate in the human stomach and metamorphose into a butterflies." Most observers would find that response annoying instead of being relevant to the conversation about nervousness.
Sure, there can be other motives such as helping someone conquer stage fright but hopefully you agree that correcting someone with formal biology definitions of "butterflies" does not achieve that objective at all.
