How about this question: Is stealing bread illegal?
Yes.
I would answer: Of course stealing bread is illegal.
Yep, I'm with you.
You: "In what jurisdiction? Can you reference a law?
It wouldn't take long to dig that out. People have been prosecuted for stealing bread many times i'd imagine. However there aren't any instances of people being prosecuted for stealing Bitcoins, so you are making an unproven assertion.
Me: "WFT man, everybody knows its illegal to steal stuff."
It's not
always illegal to steal stuff. Check out the post I made earlier in the thread about that sword incident in China. Legal theft in action - and it's a very similar thing to Bitcoin.
I would hope that laws would be written to cover theft of property, the law does not have to name every possible item that could possibly be stolen.
Well laws are mostly pretty old, especially ones which deal with fundamental crimes such as theft. Here in the UK the Theft Act was written in 1968, when the idea of an item existing purely in the virtual world was science fiction. There were electronic funds transfers though, but those transfers were backed by hard currency somewhere or other. Bitcoin is backed by nothing. You can't take it out of the bank, it is purely a virtual item. To expect people to legislate for something like this back in 1968 is asking too much.
No laws name every possible item or have to, but usually they name one (or both) of two main types of legally defined property: tangible property, and intangible property. Tangible property is the stuff you can hold in your hand, like bread, or money (even if you never actually see the cash money and it just goes from bank to card to another bank etc, it still technically exists, it's in a vault, and you can go and get it whenever you want.) Intangible property is intellectual property, like the copyright to a film.
Things can be both. Like if you buy an old master painting, generally the right to reproduce prints comes with it. But things can't be neither...or they are free for the taking.
Which category does a Bitcoin come under? I would argue that it is neither a tangible asset nor intellectual property. So, legally, it may not even be property at all, and therefore criminal charges can't be brought against Bitcoin thieves.
In the law, there are very few "of courses" If there was, we wouldn't need laywers.
