Much of your argument boils down to "there is more customization in 20 years of books in PF1 than I think there will be in a single book in PF2." No shit you can make a lot of things with archetypes. They have had 10 years to make a million of them.

Look at PF2 for what it is, a strong foundation. In 3 years, PF2 is going to have more character options than PF1 had in 10. That is going to happen because it has a solid modular design that allows to be added onto with a minimum of fuss and it is not saddled with a crapton of the shitty design decisions that are legacy from 3.X. To the extent that PF1 worked, it only worked because Paizo slapped on kludge after kludge to cover up a litany of shitty design decisions from WotC. Now we are starting fresh. None of the jank, none of the patched together crap. Yet we are plagued by people going, "If I can't build my Kitsune Rogue/Paladin/Knife Master/Arcanist (Occultist Archetype) with the CRB then what is even the point."
