ok, so just a question.
Lets say someone guessed the private key of the Silkroad BTC stash and cleaned it out. Is it theft?
How can that theft be proven in law today?
If someone were able to randomly guess/combine enough bits to create a h264 of the next blockbuster movie without access to the original film, is that copyright infringement?
If you're able to guess the combination to my safe and you take all my money is that theft?
What if you guess the password to my bank account?
If you guess my credit card number?
How do you prove ownership of a bitcoin account number? ( insert wharrblgarbl about private key here )
It's not a tangible thing. There's no door to open, no physical goods to steal. It's intangible.
If you have the private key, you own the coins.
