So you recognize that a right and no-right cannot coexist?
That one's complicated by several concepts being confounded.
The right to sole exploitation of a given item does make sense in terms of duties imposed on others and as you say doesn't make sense in terms of a right not to be exploited. What I was aiming for there was some way of saying that others should acknowledge your labour if you are the creator - they shouldn't exploit your labour for their gain - they have, that is to say, a duty to not do that.
I was however hoping to expand the terms of the exploitation, and that perhaps generated the vagueness of expression. I was hoping to suggest that there are other aspects of created products to exploit beyond the financial. Any created product (or service) exists in a context of other people's work and benefits or is even shaped by whatever legacy or tradition it fits into. Whatever innovation is included in a given object that makes it different from all previous creations is certainly a valuable part of the product, but it is, in general, just one part. Reason I raise this is I think it might well be true that whatever tradition or scene gives rise to your product, that tradition or scene also contains elements of payment.
The most obvious payment element of any "scene" is the money. Rock and roll pays for performance in pubs, clubs and stadiums. Audiences pay for recordings. The shape of this kind of work is to some degree dictated by what the pay off is. Rock and rollers live that rock and roll lifestyle because it gets paid. (And punkers react to that kind of scene and get all anti, so even if it's fun to play, they're probably not saying show us the money. Or at least, not publically saying show us the money.)
If financial reward were removed from, say, rock and roll, I guess the days of stadium rock would be over. But pub rock might survive. Producers might keep working in their basements with just their pc and a bunch of software. "Music" would go on. "Payment", aka reward, would change, and the scene would too. Same for other arts maybe too. Television might turn into something else, but do people watch tv anymore anyway?
In an age of digital copying, whatever can't be copied is what gets paid. Now obviously everything can be copied. Live performances can be captured on an iphone and uploaded. But that recording doesn't capture the next live performance.
Writing is what suffers on this scheme. What can't get copied about a novel these days? What can the author claim as uniquely hers and worthy of "payment"?
(Actually, my wild guess is her next book is what can be bought, and readers buy it before it is written - the author does a kickstarter and that's how she gets paid. But that seems like a crappy way to earn a living. Except that actual authors probably live just as crappy an existence already so, whatevss...)
