we need a new unit to unambiguously describe angular measure.
That's a nonsense unit. You'd need to know where my eyeballs are and change the measure as I move my head around! What happens if two people are looking at the screen?
we need to start demanding resolution independent units
That's what CSS pixels are. A pixel is 0.26 mm, period.
Right but that's just "for lower-resolution devices", i.e. devices with a resolution lower than the reference pixel. There's no use demanding to have units of measure which the device is incapable of displaying! What possible use would it serve?

For some definition of "mm". Did you read the part about "anchoring"?
