The point is that scientists use units appropriate to their domain and community. The general public uses units appropriate for their uses. These usually do not coincide. There would be advantages (e.g. for standardization, "science literacy") if they used the same units but it would also be impractical for whichever side adjusts to use the other's units. I believe the advantages of such a switch are very small and the downsides small. Neither scientists nor the general public seem to think this is a problem.
