Because early Denuvo cracks tend to not work correctly, and often require you to do stupid shit like set your OS's year to 2015 or something like that just for the game to boot.

I rather just wait a year or two for either a proper crack, or for the developer to decide to remove the DRM themselves, a la Capcom. Especially it's a single player game, cause there's no need to worry about the player population dying down by the time a crack comes out. And you also get to reap the benefits of having bugfixes available since the game has been out for awhile.
