Copyright is a concept from an earlier era when copying something required both, a somewhat unwieldy machine, and a physical object for each copy.
indeed, ownership is already about who has rights but it is also limited by the nature of whatever is being owned.
If we focus on inescapable constraints, i.e. not those imposed by society (which are arbitrary and can be changed), it turns out that technological developments have removed some of those constraints.
All you do is ignore new possibilities (and their accompanying new problems) by holding on to legal notions first introduced in the 17th century.
