I think part of getting by with a lower PPD is the IRL pixels are fixed and have hard boundaries that OS affordances have co-evolved with.
(pixel alignment via lots of rectangular things - windows, buttons; text rendering w/ that in mind; "pixel perfect" historical design philosophy)
The VR PPD is in arbitrary orientations which will lead to more aliasing. MacOS kinda killed their low-dpi experience via bad aliasing as they moved to the hi-dpi regime. Now we have svg-like rendering instead of screen-pixel-aligned baked rasterized UIs.
I'm not sure most of us do anymore - see my 1080p/24 inch example.
No one who has bought almost any MacBook in the last 10 years or so has had PPD this low either.
One can get by with almost anything in a pinch, it doesn't mean its desirable.
Pixel density != PPD either, although increasing it can certainly help PPD. Lower density desktop displays routinely have higher PPD than most VR headsets - viewing distance matters!
