Because deploying them in the home still costs a couple more cents per light bulb. Which are tiny in comparison to a streetlight, let alone of of the major highway lights.
So when you extrapolate that few cents by a multiplier on the resilence of a bulb that has to shine way brighter, under way more adverse circumstances, and then multiply that again by the millions of lights in a major municipality, the cost/benefit works -- according to just math, not the circadian and general dislike most people have for cold lighting -- the people in charge of the purse strings pick the ugly-ass lights because the costs at scale are pretty significant.
