You are categorically, factually wrong.
I have personally completed Library of the Lion and The Bronze House Reprisal without once rolling initiative. In both instances it was fully intended that this be possible. There are other scenarios where this is also possible. With a good GM, there are several other scenarios beyond those.
There's more than one way to play Pathfinder. Stop insisting people play your way.
I downloaded and read through both scenarios...and concede the literal point only. Now show me how to play an entire career where you, even in theory only, never get into a serious scrape and I'll concede a character doesn't need a solid plan for surviving and contributing to combat in some fashion.
I'll do you a favor and exclude Seeker play, so that just means you need to find 31 more scenarios where there isn't an instance where it is not stated as inevitable the PCs run into a force that will automatically attack them regardless of any skill check or decision on their part. Heck, I'll go ahead and make it even easier - if the CR is below the level of the tier, it doesn't count as a "real" combat for this purpose.
By the way, I'm not calling you out here. I'm genuinely curious - I haven't played very much past season 4, and only dropped in because I started running an AP. If I'm wrong, go ahead and prove me wrong.
