Re: Let's pretend the internet doesn't exist for a minute... bear with me...
Well that is the truth, someone can steal your number-plates and not just number plates, whole cars get stolen. But the difference once again comes down to cost-benefit.
Whilst it's trivial and would take less than 3 seconds to steal a print left on the street, even less time to Ctrl+C and copy an image - for a small amount of risk and storage space. It's a bit more risky to steal a car in that you can't hide it up your jumper and you can't hide it once it's in your possession (without paying a lot more than a picture for storage space).
That's even ignoring the fact that you can take a picture of a picture and you can create a slightly inferior copy that you can enjoy. You can't take a picture of a car and say now I have another slightly less quality car to drive!
So I'm not sure how you defeat my analogy? It just makes me think you didn't really read my comment and neither did those who upvoted you. Why even bother replying?
