This analogy is also wrong, exactly for the reason that IP is not a physical thing that can be taken - it can only be copied.
Yes, by leaving $0.40, I would be stealing $0.59 of foregone revenue, but that is because the shop doesn't have that candy bar anymore and can't sell it. In case of IP, even if I pirate it, you can still sell it to other people.
Of course you probably can't sell it to me anymore and that may be lost revenue, but it depends if I would be actually willing and able to buy that IP otherwise. And of course it may cause more competition to appear, which will negatively affect your business.
