"day-to-day practical measurement" as distinct from what?
Theoretical physicists might be able to skip the units, but the rest of us farmers, engineers, cooks, are doing something practical when we measure.
I'm not really sure what you are arguing.

However, think of it this way: In conversational transfer of information, it makes zero difference. If I'm telling you something is 300 miles away, it isn't more useful for me to tell you it's 480 kilometers away. What extra information do you get from that? That it's 480,000 meters away? Humans can't properly visualize probably more than 100 meters. So what practical use when calculating driving distance is knowing that Kilometers vs meters the distance is?
Day-to-day using miles or inches for distance, gallons for volume, and now we have specialists using miles-per-gallon for fuel efficiency, cubic inches for stroke volume ...
