First off, chronology is important in discussions. Your "systemic flaw" post came after my post you quoted.
But on to your argument. Accesso, the company handling the virtual queue system, is arguably the industry's premier "Queuing Theory and Technology Company". They understand that the guy who would pass on jumping in a 45 min. line where he would spend 45 mins. standing on stairs would likely "Tap" to join a 120 min. virtual queue. That's the appeal of "virtual queues", not standing on stairs for 45 mins over and over all day.
And, in truth, the "queuing system" seems to be working just fine. People just aren't liking the answer they are getting. What seems to be the main problem isn't the queuing system as much as through put on the attractions. You want your most experienced ride ops on near capacity days. Instead they have poor TMs that are flailing miserably because, well, everything. Untrained, inexperienced, tech issues, down times, too much of everything, not enough of anything. Accesso knows the theoretical and estimated real world HRC of each of the attractions. If the ride ops can get close to the model numbers, the system will be fine.
I do wonder if they regret pushing the mammoth to phase 1.5?
