Their wired stuff is a total scam since Edgerouter fell off, though. The same functionality exists on a $50 netgear managed switch (or wired router, etc.), and the shitty unified configuration interface doesn’t justify the markup at all.

Sorry, but what markup are you referring to?
I'm sure you can find price differences at different products & tiers, but quickly glancing around it sure doesn't look like Ubiquiti has any particular premium markup.
Regardless having a self-hosted, buy-it-and-own-it, non-business friendly product line absolutely has value. I loved my mikrotik switches when I was just messing around, but the single pane of glass, central management is not insignificant when time becomes a more precious resource and you just need it to work.
Which is how I'm using mine actually, one less wall wart in the area I use them
