> every method of value extraction has overhead so something can both be valued and have no economic value

Right. Which is why I don't bother selling on ebay or amazon, it isn't worth the time, postage, or trip to the post office. It just goes to the thrift store, as they have a business model that enables them to eke out a profit on such items.

yet books that compile publications from previous centuries are published and bought but evidently the ledgers are not debited or credited for the parties to these transactions. Basically if a method of value extraction has so much overhead that it has no economic value I would expect that method to disappear, thus when methods of value extraction are still in use I think that someone has managed to derive economic value from that method - perhaps a very paltry economic value in comparison to some of the companies we discuss here quite frequently - but still some value.
