So by that definition somebody who takes your Bitcoin isn't a criminal, since Bitcoin is not physical. Nice.
Bitcoin ownership is exclusive. If you have received 1 BTC, other person have lost it.
But you implied above that since intellectual property does not have a physical manifestation, it is somehow not property that should be protected by law. Both Bitcoin and intellectual property are non-tangible assets. Either you believe these should be protected or you don't.
BTW, even in case of Bitcoin theft nobody will go to the state authorities in my country because very likely even legitimate owner will be charged for "money laundering", "terrorism financing", "illegal banking operations" or similar.
That's awful. That's not the way it works in my country, thankfully. Here in the USA, if somebody steals something from you, you go to the authorities. That goes for physical things like your car, or non-tangible things like Bitcoin or your copyrights.
I hope you don't wish for the whole world to work the way your country does, because that sounds like a pretty bad place.
