Yes, absolutely, even just in the private copying system. Once people no longer use blank audio media, which are currently covered by the act, there will obviously be a dead loss in this area. Reproductions could be made without there being any financial compensation.
The same is true for the reproduction royalties currently paid by broadcasters, although, for the moment, those royalties, at least for Artisti and its members, are much lower than the royalties resulting from the private copying system.
