I get what you’re saying. But, do you get what I’m saying? If someone asks “why is X Y to you”, the answer “because it is Y to me”, doesn’t add much. Now, the OP asked for a reasoning for why it was ethical. You have pretty much said “fuck ethics, I do what I want”. And, as you very much point out, you do not care what anyone thinks. Which… I find weird to point out in a discussion forum. FYI, ethics tries to be a little bit more general than “anything I want is by definition ethical to me”. I’m sure we’re both happy to leave it at that.
