That "small tour" (with a session drummer) is currently standing at 56 dates and I'll be surprised if there aren't more. Given the short timescale from the initial announcement of 11 gigs, for an event of this scale all of those additional dates & venues must have at least been reserved in advance. So those 'unhappy' fans are clearly willing to bend over & accept the sphincter-ruining ticket prices, however much they may complain, and the band/management would have had a pretty shrewd idea that's exactly what would happen.
I'd be very, very surprised if the band weren't well aware of, and getting a pre-agreed percentage of the outrageous prices - I don't think any of the tickets & packages are a consequence of dynamic pricing - that's just what they cost.
I first saw Rush in 1981 and I'm quite saddened that even going back that far, I never saw them in a venue smaller than the colossal, soulless, acoustically disastrous sheds that 'big' artists tend to play. I detest these venues with a passion & at this point I don't think there's any band I'd be willing to pay 3 figures to 'see' (through some f*ckwit's phone screen waving in front of my face) in one. And that includes 2/3 of Rush!
