I think you're missing my point.
When little Johnny or Susie is introduced to Disney parks as a young tyke through repeated visits, my premise is that he or she can be imprinted with overwhelmingly positive feelings that extend into adulthood and adult buying decisions.
If those visits aren't happening as often, then 20-30 years down the road those warm feelings from childhood won't exist and those decisions to buy Disney products or services won't be made to the same degree.
At that point there will be no "react accordingly" for Disney with respect to that group. Sure, they can re-price their offerings then, but they will be sacrificing revenue then, and they won't have as loyal a following as they might have had.
I suppose the real premise is that there is a Disney culture into which people are encultured very young in many cases, and it drives irrational behavior (see $100 popcorn buckets).
It's an abstract argument, but one I can anecdotally defend by pointing to our kids. They went to WDW multiple times growing up, and they are now taking their families to DL and WDW, buying lots of Disney merchandise, streaming WDC content, etc. Yes, it's anecdotal, but I see it. And I can't help but think that today's pricing will shape the number of trips many families with young children will make.
I agree, like all financial decisions it comes down to a value equation. And Disney has enjoyed in many guests a strong value factor being goodwill. That "Disney Magic" has justified high pricing. My sense is Disney has edged to the limit of that pricing, and I think there is a real risk of them discouraging some/many families with young children from coming as often or coming at all, and that may translate down the road into a smaller population valuing "Disney Magic." Whether that's true or not won't be knowable for several years.
