I can't argue with the statements made in the original post other than the comment about the setlist. I'm sure the band has retained full artistic control over their shows, such that they're the ones deciding what songs they're playing. Other than that, I'd say your general discussion about pricing is pretty spot on.
Biggest mistake they're making in the whole scenario, though, is that they continue to price GA tickets well BELOW what the market is willing to pay. I'm pretty sure that this is a band decision, not a Live Nation decision. That forces some of the tickets for seats into the higher price ranges where the market is saying that they shouldn't be, as they're not selling. To have tickets on the floor priced at $76-$80 while everything comparable around them (basically the whole lower level, except for limited view areas where the ticket holders can't see the screens) is priced at $330 or more clearly indicates that these tickets are priced way too low. Those tickets, then, become the ones the resellers most want, as they present the greatest opportunity for good profit margins for their original "investments." Thus the immediate situation where demand (both by real fans and by resellers) outstrips the available supply straight out of the gate at the onsale. If GA's were priced at face values of $200-$250 initially, this problem wouldn't occur and probably all of at least the upper level seats could have been priced more reasonably. Would there have been bitching and moaning from the diehard fans that are used to getting floor tickets at prices below Fair Market Value? Sure. But we wouldn't have been seeing what's going on now ---- overpriced uppers going unsold and diehard fans bitching and moaning because the only way they can get GA tickets is on the resale market at prices that are roughly 200-400% above "face" (where they should have been priced to begin with). The end result is a scenario where the band is "trying to have it's cake and eat it too," because their shows are now overpriced in a lot of areas (making sure that the artist is not "leaving money on the table," as the original post describes) and yet still under priced for the tickets (GA floor tix) that get attendees closest to the stage and band (with the exception of the Red Zone tickets).
What we're seeing is proof that you can't do both. Either you price your tickets such that the resale market has some opportunity for re-sellers to potentially make a profit, or you price everything high enough that re-sellers are really taking a risk when they speculate on their ticket "investments" by buying ticket inventory that is pretty much priced at market to begin with. It will be interesting to see how this all plays out by the time the shows occur. At the outset there clearly were some pricing mistakes made. In my opinion the biggest is the continued "under market value" pricing of GA tickets and that can't be corrected, as those tickets are all sold. As for the rest of the unsold inventory, yes, there will definitely be price adjustments taking place - whether "disguised" or obvious - or there will be empty seats at many of these shows. I doubt the latter will be allowed to happen.
