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.
I do wish they were even smaller (I've got one location I'd like to mount one inside a wall box, which is admittedly pretty niche), and I am never again touching UI's configuration software (even 10 years later I feel that wound), but, yeah... love these little guys.
Which is how I'm using mine actually, one less wall wart in the area I use them
