For myself, my smart glasses use case involves darkening headlights of oncoming traffic as I drive at night. The road curves a bit in parts of the city I live in, and the headlights shine in my eyes. It's not worth 5,000$ but car insurance also feels expensive until I need it.

Even then, look at Android. Graphene and similar are pretty good base operating systems, but almost the entire app ecosystem is corporate spyware.
this is very true, but it also has a huge FOSS app ecosystem and highly polished FOSS apps.
I've recently been having Codex patch closed source apps making them work offline and greatly reducing their permissions and it works really well.

Patching binaries of such mandatory garbage is a nice idea though!
This could solve the main problem I had with graphene in the past, which is that some applications I had to use (like for parking or charging a car or whatever) crashed on startup with a Null Pointer Exception, and the set of broken apps changed from week to week.
I imagine binary patching could be used to bypass hardware attestation checks too (you'd need to extract the key from the enclave, but that's usually pretty trivial, depending on the phone model). None of the apps I used required that.
The apps you use, sure, those are also optional, but using those same apps on a desktop would give them even more information about you and more power over your system.
Phones will always be worse for privacy. They are festooned with microphones, cameras and a variety of radios. The PC I am using to type this doesn't have any of those things.
You can't. "Airplane mode" doesn't actually shut down everything. Carriers can still track your phone. https://undercodetesting.com/how-your-phone-tracks-you-even-...
Your phone also still collects a record of your GPS data, and that history gets transmitted back the moment you have a connection. Your phone can also still be tracked via bluetooth while in airplane mode. That's also how "find my device" works when your phone in airplane mode. WiFi data can also be collected while in airplane mode.
Airplane mode is basically a lie. It's prevents the transmission of certain specific signals from your device, but that's about it.
Which model?
It's there any infra for it? As in downloading face data from Facebook and the like.
Why stop there? Stream the camera to a CNN and black out all the ads in real time you'd other wise be forced to see walking down the street or in the subway.
Except for those of everyone else around you
At that point I will be able to have the fun of AR (gaming with paper toys or other papercrafts, displaying characters on a table for my tabletop RPG group, getting directions in a foreign city, identifying plants and insects just by looking at them, seeing where my cats are located through walls via their airtag collars) without any ads, without any data harvesting nor privacy concerns, and even being able to write my own custom apps or firmware mods. It will still be a toy rather than a necessary part of life like a smartphone has become but a fun toy nonetheless.
