I never insinuated it was. However, he lost his friend, a founding member and the face of the band. In addition, half the songs were about Layne. I've always had a world of respect for Plant for putting Zeppelin to bed after the passing of Bohnam. Jerry should have followed suit.
You've merely chosen the exception that proves the rule.
It's relevant to his intentions.
Yeah... like anyone cares who the other two guys are. 99% of the people who will show up to these shows wouldn't even notice if Jerry replaced the rhythm section.
He can make whatever music he wishes. If he hooked up with a talented singer who was completely different from Layne, I'd be curious to hear it. This is a move to replenish his 401K.
Come on... he's a clone.

Irregardless if AC/DC is the exception, there is still an exception to your "rule", thus proving a band can go on. I'm sure in 1980 there were Zod's going "It's not AC/DC without Bon".
I care who's in the band. And would not show up if it wasn't the other guys, just like I don't show up for G n R and Megadeth shows. While it is true that a lot people might not care who's in the band, your point is moot because it is the guys who were in the band.
Duvall is not a clone. He has been touring with Jerry BEFORE Layne died. No one made a big deal of who he was until they started doing shows under the Alice name.
