But huge numbers of people apparently value the works we do produce today that have those expensive production values, and in the case of works created for utility rather than entertainment, the usefulness of the work may drop off rapidly if it's not as well made.
Technology has changed the landscape, and unless you're willing to live in a police state with strict regulations on general purpose computing and communications technology, that genie isn't getting back in the bottle.
Technology has changed many landscapes, but just because we can do something, that doesn't mean we should. Most people recognise that certain acts are harmful to specific people or to society as a whole, and we legislate to make those acts illegal. We can certainly debate whether copying a knowledge work under various conditions is such an act, and if so, whether copyright is an appropriate response, but I don't think "This is the way the world is, deal with it" is a compelling argument. Anarchy would be very unpleasant for many members of society.
