I also think he underestimates the continued power of the original films. As a Millennial, I was first exposed to the OT on VHS in 1993 or 1994, and I imagine for many Millennials up until 1997 it was the same way. My little brother may have first watched the '97 versions, but there are several generations who were raised exclusively on the unaltered films, and who never cared for the prequels despite being children when they were released.
And all this is ignoring the argument for historical preservation and simple decency in preserving the work of those who originally made the films, such as the craftspeople who did the matte paintings and model work that has been simply erased. It genuinely makes me mad when people say ‘no one cares lol’ when for most people, they have been deprived of the opportunity to care by a generations-long campaign of artistic suppression by the most powerful entertainment companies on the planet.
