The idea that if I remotely hack your computer, email account, 'steal' your bitcoin by guessing your seed etc. it's a crime, goes against property rights, just like intelectual property rights contradict normal property rights. It's deeply statist and anti-cypherpunk.

If I break into your house and gain access to your computer then yes, it violates the NAP, because it's trespassing and touching your stuff without your permission.

But if I do it remotely, I'm sitting in front of my computer, in my house, at my desk. I'm pressing keys on my keyboard. Since those things are mine, I have the right to do what I want with them; if I didn't, in what sense would they be mine?

Now, you may be running an SSH server or a remote desktop server on your machine that you perhaps shouldn't. You have ports open that shouldn't be. And your password is weaker than it should be.

My keypresses cause my software to talk to network protocols, which talk to your server. And your poorly set-up server is interpreting them in a way it shouldn't. It's picking up and acting on signals it shouldn't, which grants me access to stuff you didn't want me to access, but did let me access, through negligence.

You only have yourself to blame.

This doesn't mean I'm not a jerk by accessing 'your' stuff, but it's not a violation of the NAP. I didn't sign a contract that said "I won't hack your computer." Neither did I deceive you. I 'deceived' your software, but software is neutral, it doesn't have free will, it just follows instructions given to it. And you happened to set it up in such a way that it listened to mine.

Moreover, once I've 'stolen' data from you remotely, it's no longer exclusively yours. It's mine too, because information is a non-rival good.
