I didn't "steal" your passwords, I just "copied" them. I don't know what you're getting so upset about, you still have your list of passwords, and the fact that my changing all your accounts' passwords rendered that list worthless did nothing to move it.

If someone steals my passwords and then does nothing with them, or just uses them for their private purposes, then there's no problem. The problems only occur if my passwords are used to take control of my accounts or identity, which would deprive me of my accounts or money etc. So your example actually reinforces that the relevant ethical distinction (the harm) is indeed in intending to deprive someone of something they possess/control

I don't think this is the case legally, it might depend on the facts, but usually passwords are stored on your systems, and an attacker would have to not only access your system, but to exfiltrate that data.

It would constitute computer fraud and abuse by most definitions. This is relevant because it is sufficient to prove someone has your passwords in order to convict them, you don't need to prove they used them maliciously. (Provided of course they are a third party with no legitimate reason to have your passwords)

Stealing has a much looser definition than theft; notably, it can include ideas unlike theft. You deprived me of my accounts, but not of my now-obsolete passwords, therefore it's a theft of my accounts, but not theft of my now-obsolete passwords; I suppose you stole both. I'd be upset despite lack of password theft because I'd be the victim of your CFAA violation for example.

You copied his password? *******?

(I really hope that was an intentional reference or this won't make any sense.)

See, you typed hunter2 but all I see *******.
