The biggest takeaway for me is the WATA/GoCollect/Hertitage influence brought in a new tranche of people to the hobby.
This is a tenuous analogy...hang with me......but the new "comicbook" crowd feel like the rich people from developed countries that travel to a relatively poverty stricken vacation destination. They bring in their strong foreign currency, spend "lavishly" relative to locals, and only stay at a few choice spots. Choice spots = high end sealed games. The economies in those destination cities/towns completely change (sealed and certain CIBs skyrocket) as the locals (old collectors) cater to the new tourist money (comicbros) as prices soar. The surrounding cities (lesser CIBs, set collectors) in that same country that the tourists don't travel to as much may experience a slight inflation rise (reasoning for so many "nos" on this poll) due to the knock on effects of the influx of new money (workers flocking to beach resorts to work for more pay = wage rise in other cities).
In the end, some locals are better off (monetizing pieces at record prices), some are not (set collectors, CIBs, non-nintendo pieces), but overall it feels disingenuous. Outsiders have seriously impacted the economy and the culture and they're doing it because it's cheap holiday (or cheap investment in their eyes) and not because they truly care about the island (or games).
I think that's what bothers me more than prices going up. If the core sealed collectors for whatever reason just started to get more aggressive, and prices began to rise organically from a group that truly valued the nostalgia - that feels good to me. Sitting here watching thousands and thousands of dollars dropped on graded games they don't give a frog's fat ass about feels bad man.
