Re: OTT?
“Copyright is in principle a good, as it protects creative output …”
No, copyright impedes genuinely creative output. Ideas lack the properties necessary for being marketable products. Copyright depends upon shoehorning ideas into a pseudo-market protected by legal monopoly. Properly structured market-economics eschews monopolistic practices.
The only true commodity is imagination and skill for developing ideas and, when suitable, applying them. These attributes exist in individuals and in groups working to common purpose. People/groups must compete for attention and the prospect of commissions (e.g. via crowdfunding) to enable them to realise their ambitions. Reputation is what they bring to the market in competition with similarly inclined others. To maintain order, it is necessary to recognise entitlement to attribution, and to have legal remedies against people intent upon impersonating successful players in the skill-market, that done to obtain undeserved patronage.
Barely recognised by profiteers from trading copyright is an ethos running in parallel yet wholly dependent upon free flow of ideas in a context of sharing with strict attribution and encouragement of 'derived' works. The standing of a scholar is linked to his impact upon his peers; impact is best demonstrated when other people take the baton and run forward with it.
In the days when the only way of disseminating information was by distributing paper copy, publishers made a major contribution to academia. Gradually, within the dogma of copyright, they sought to assert a high degree of financial ownership of that which they propagated. Their restrictive practices now stifle access to knowledge and thereby hinder education and scholarship. The arrival of such as Sci-Hub and LibGen were of an effect like a sorbet served after a stodgy course at a banquet.
A broader point arises. An enforced attribution culture, one wherein it is creative skills rather than digital end-products which are marketable, should apply across the board of human activity. It would include the highly profitable for some, trashy element of popular culture. That component would be restored to the dynamic of former folk culture, wherein 'derivation' and freedom to explore facilitate participation rather than passive endurance. As with academia, 'derivation' (with due acknowledgement), is the sincerest flattery.
The availability of money to support cultural endeavours would increase considerably because a huge raft of copyright rentiers and middlemen could be set to useful work digging ditches. No longer would a large proportion of individual and national disposable incomes go into the pockets of parasites whose only encounters with creativity entail its application to accountancy. Moreover, taste and whom to laud, would cease to be dictated by monolithic commercial entities. A return to individuals and cottage industries surviving on their wits. A massive bonus accrues from consigning a swathe of lawyers to manual labour.
