Impersonators are recognizable, and assuming an identical one can be found, it would require a lot of time, during which the most money would have been already squeezed from the artist repertoire. In contrast, they're probably aware that it's just a matter of time until AI technology will allow to build an identical copy with new seemingly authentic material in one day or less. They're fearing the day powerful AI can be freely used by everyone in uncontrolled way, so that piracy won't even be necessary anymore, because one could simply ask to their local AI terminal: "hey, wake me up tomorrow at 7.30 with Sinatra singing Back in the USSR, then play Pretty Vacant by the Sex Pistols, but sung by Amy Winehouse, while I'm having breakfast". Digital models of artists will become the new big thing that day.
