alt Hacker NewsIt encourages creation of new works just fine, but at the expense of creating billions of tiny monopolies that last for generations, which get aggregated into huge monopolies, ultimately making ordinary people into criminals for wanting to preserve or modify the works that make up their culture.
My point is that it doesn't need to do that. Copyright could still encourage creation of new works with a much shorter duration, without the downside of locking our culture up in monopolies for life + 70.
None of that contravenes the purpose of copyright in encouraging the creation and sharing of new works.
You could equally solve the issue by providing provisions for archival. Or a provision that requires a work to be freely available for sale.
The creator having a monopoly on the work seems to me to encourage the creation and sharing of work as intended.
