"Property" is a useful social tool for managing stuff that is scarce and which can't easily be shared. Food, tools, shelter, land, and so on. Property produces stability. People can count on having their stuff later, even if they're not using it at this instant. That lets them make longer-term plans, which, ideally, result in lots of different kinds of things becoming less scarce.
Ideas and information, however, are not scarce. Any number of brains and storage media can hold them simultaneously. That's not true of a pizza. But for a long time "intellectual property" worked pretty well because the copying of ideas and information required significant effort and materials. Books had to be typeset and printed. Music had to be stamped onto vinyl or written onto tape, which needed specialized equipment. All this made it so that we could pretend that ideas and information were scarce.
Now, that's not true anymore. Our technology has advanced to the point where the equipment for copying information is ubiquitous and unspecialized. We have to face the actual nature of information: It's not scarce. "Property" doesn't work on it anymore.
Which really does leave artists and authors and other intellectual producers in a bad spot, since the time and effort involved in creating stuff hasn't gone down. We have this kind of thing now where it either doesn't exist at all or it exists in such abundance that the adjective is unneeded. How do we economically incentivize something like that?
Personally, I lean towards the suspicion that for some kinds of things, mainly entertainment, we don't need to incentivize it anymore at all. People are not going to stop writing fiction and recording music just because it doesn't pay anymore.
The real jam is in non-fiction, because that costs of making that stuff are higher than just food and shelter for the producer while they're writing. Research often requires travel, experimentation, equipment, materials. How do these get paid for?
