Thanks for the answer but the question here is different.

I will start with an example when you buy a song via Itunes, you bought a copy of that song, which is sold under whatever license right? With bitcoin its different, the MIT license says that you might use COPY of the bitcoin software in all the way - opensoftware. But what I want to know is whether the bitcoin is the money, coins, medium of exchange, is the COPY of Nakamoto's original work or whether it's the original itself. Every Bitcoin is unique and can not be copied as the network would not accept it. It is even possible to say that all of the bitcoins already exists. does it mean we use the very first, yet updated program of satoshis, which integral part is the 21 million of bitcoins?

The copy of the program are some altcoins that took the code. The copy of the program is probably something we use to enter the network. But the network itself is it a copy?
