The purpose of a layered DRM like Denuvo is not just prevent piracy or other silly notions like annoying pirates. If the raw data the publishers have doesn't end up resulting in extra units sold than their previous release of an IP in the same timeframe from release (not lifetime), then it must mean that the service is incredibly affordable to the publishers that they don't even care about ROI.
Pirates don't buy games and it's a long known fact that the publishers are aware of, way before us, consumers. But the fact these anti-tamper solutions make them think twice for a purchase is both, a potential consumer at hand and good for the platform in hindsight for developers to invest (time and momey) in & take it seriously. It's a necessary evil that we have to endure until there's a new way write a game's code which prevents it entirely from reverse engineering (yet supports mods) or a new physical media that with a high storage enough and read speed.
The only thing I would be worried about is mods and that doesn't look like a problem in the future with Denuvo equipped titles like Dragon Age Inquisition, Mad Max and V having mods. Its a start, since previous releases like Lords of the Fallen did not. Online MP-heavy games like Battlefront or BF Hardline won't have them anyway. Also, V was partially cracked by pirates? Whatever that means?
Oh, and piracy doesn't mean game preservation, sorry, it doesn't even makes sense. A Denuvo title is likely released within the last 2 years and it's publisher is most likely active in development for future titles or in extreme cases not concentrating on video games as their primary source of income anymore, like Konami. It DOES NOT MEAN that V and other Konami games get delisted as soon as they move to pachinko/pachislot. Their main source of revenue has changed. The games WILL exist as long as Valve/Steam do, and generate money for Konami on each unit sold, as it rightly should.
Preservation only becomes a problem in some highly unlikely scenarios of a (public) company (publisher/developer) getting their shares/assets dissolved and their games left in limbo. Long term preservation should of course happen, but an alternative, like a govt stepping in with a digital archive long after the games are on sale, but NOT PIRACY.
