Exchanging stuff is absolutelly natural (you see little children doing it) and extending barter trading to "trading for tokens which can be exchanged with different people for other things" is really just introducing a new type of item being exchanged.

Going from sharing of ideas to not-sharing, on the other hand, is going for doing something naturally to the very opposite of that (hence my use of "anti-natura").

I don't think "exchanging stuff but now with tokens" is at all comparable with "stop doing what you would otherwise naturally do without even thinking about it and bring into this exchange an unrelated 3rd party".

I feel like you're trying to hammer a square peg in a round hole there: Copyright Legislation is not about the natural give and take in a exchange or trade (in this case of information) but rather it involves a 3rd party, which is not even present, which is the owner of the copyright of said information (used to be the creator, nowadays it can be anybody or a company) who is artificially inserted in what would otherwise be a normal exchange between 2 persons as an additional externaly party that also requires something.

I suspect the recurrent confusion of so many between copyright violation and theft is exactly because copyright is entirely unnatural, so people fall back to the closest instinctive human behaviour to try and understand it, ending up with the completelly way out there incorrect idea that copyright violation is like one side in an exchange taking stuff from the other and running away before giving their stuff to the other, when in reality you have to sides doing an absolutelly normal exchange (or even a gifting) and there is a 3rd party, not physicially present and never met, seen or otherwise involved with either which the powers of the land say is supposed to authorize that exchange and get a cut if it so wishes, and which both parties of that exchange choose to ignore.

It's not theft because both parties on the exchange are conducting a normal exchange just like they do with all other classes of thin and both are abidding by it. The closest "normal" illegality to copyroght violation is tax evasion and not tax in a democratic nation (were the money goes into the common pot to help everybody) but rather tax in an absolute monarchy or dictatorship were whomever was supposed to get that cut from that transaction is going to keep the money and even then the analogy fails because your're also supposed to give that 3rd party money even when GIFTING something.
