I have just found your netbook on the backseat of a taxi with it already logged into your bank account. So that makes it okay to transfer your life savings to my account, right?
No, this is about whether it's okay for you to remember how much money is in the account, and act on that in some manner in the future. Nobody is stealing anything. They can have the pieces of paper back if they want them.
So I will just email myself a copy of your work and patent it before you can.
No harm then right, it is just a copy.
