You can be honest or dishonest and it will be encrypted and decrypted all the same.
Your second argument to me doesn’t follow. You are saying what you say and do is more important than what you value, I think, but you are also saying that what you say and do are not important so you can be dishonest.
My conclusion is that you prize winning over being ethical.
Just think of all the other cases where honesty and ethics have been put on the back burner on the basis that you think your thing is more important; a lot of them legal.
I do not prize winning. I'm not sure who is "winning" or "losing" when I decide to not publish my name. I'll note that I use my real name and attach my real identity to lots of things. I just don't agree that people who choose to mask their identity through a plausible persona are somehow walking an ethical tightrope. They are entitled to use a fake name.
I am not sure I follow - what we say and do is who we are, how could it be otherwise?
As a person who prizes the idea that what we say and do are more important than who we are, I disagree that honesty and ethics always align. If some dishonesty maximizes peoples' actual wellbeing, then that dishonestly is probably actually more ethical than the honesty that compromises and hurts people for no gain other than ideological purity.
