I'm not very knowledgeable in this area, but have a question, as you seem to have thought about this.

I feel the GP's point relates to things like corporations receiving favorable tax treatment when individuals would not; corporations receiving very lenient punishments for crimes when individuals would not; corporations, as above, being able to avoid payments when an individual's property might otherwise be at risk, and so on. Perhaps I'm just not aware that these possibilities are available to me. Am I mistaken here?

Overall, I feel your response deals with the legal framework around what GP said as opposed to the ideas that inspired GP's comment.
