I hate to agree with you, but you're right to an extent.
Ironically you are also backing up Jim Ryan's parting sentiments on PC (Steam most prominently) being a competitor to platforms like PlayStation. Because he was 100% right. Which makes the sentiment of conversion Herman & Hideki express (and what so many PS fans are now parroting) seem laughable.
Yes, SIE will maybe convert a small portion of some Steam users to get a PS, maybe as a secondary platform. But if they're only going to use their console for exclusives, and the # of 1P exclusives is effectively halved going forward (due to GAAS), and SIE aren't getting that much profit (if any) from the console sale, then most likely those PC/Steam converts
AREN'T:
-Buying a PS+ subscription (single-player games wouldn't require it, and that PC gamer prob still uses PC for their online gaming)
-Buying PS peripherals (chances are they'd play the single-player exclusives directly on their console; PS Portal isn't compatible with Steam so no reason for that)
-Buying 3P games on PS (since vast majority of 3P games now come to PC (Steam) as well as console Day 1, the PC gamer is likely to stick to Steam for those)
Meaning SIE aren't making a lot of money off these particular converts whatsoever. They aren't going to be high-ARPU spenders in the console ecosystem, and if these PC gamers (really, Steam gamers) have no FOMO, guess what? SIE doesn't even get a console sale out of them, because they're just going to wait for the eventual PC port 1-2 years after console since SIE have established a cadence of bringing all their non-GAAS titles to PC anyway.
Between this, PS consoles supposedly not needing true exclusives, and the talking point that you can't make AAA games exclusive to one platform anymore, I don't know which topic is dumber. But they're all obviously fluff topics engineered by influencers & media to steer gullible brand fanatics towards accepting what these companies want to push. And by "companies", I mean Microsoft plus now, apparently, SIE/Sony. Even if what these companies want ends up meaning less for you (especially if you're a console gamer), they want you to accept it anyway.
