The argument that all tectites on the moon would be destroyed by micrometeorites is fallacious. There is plenty of opportunity for tectite-rich layers to be buried by later impact sheets, prior to total degradation. So we should expect lunar preccia samples to include some tectites, at least.

The fact that they don't fits neatly with the model that tectites are formerly-molten material (perhaps even vapour condensates) that have passed through a planet's atmosphere and cooled in the teardrop or discoid shape they adopted under aerodynamic stress while still fluid.

On the Moon, there is no atmosphere, so the impact glass beads are all spherical, if small enough to chill before re-impacting the surface. There are no big beads because they are too big to cool efficiently (radiation to space is much poorer than conduction to a turbulent atmosphere). Bigger globs of molten material splash back down again, producing spattered secondary beads and local glassy matrix/cements

The blueberries are about as far from being tectites as you can get, and your ridiculous desire to classify them as such in the face of numerous lines of evidence demonstrates once again your lack of objective thinking skills, EP.

(In my mind, it always rhymes with "Pee")
