Relaxed Intensity
Or they care about games as games at the table. The char build game only became a thing in D&D with 3rd edition. To an earlier generation of players, getting through the Tomb of Horrors alive, using a pregen character, was a true test of player skill.
Char op is an element of the game that some players find tremendously engaging, and others care about not at all. I have guys in my group whom have been playing for 40 years and never so much as cracked a PHB away from the table.
Are you speaking in terms of your build determining success or in terms of there being mechanics to engage with at all?
If the former PF2 has done an excellent job of making the decisions that matter the most the ones you make at the table and would love to have that discussion. I would argue that it is a game that does not require a significant amount of time away from the table to play well.
If the latter I think some level of tuning your critique to your subject is necessary. Like I love B/X and even simpler OSR games like Mork Borg and Into The Odd, but it is obvious PF2 is not trying to be that type of game. Not even close.
