In this example we're talking about inches and an inch is not any more divisible by 12 than a centimeter. Generally you're not going to see 48 divisions crammed into an inch on a ruler. You can have a set of specialty yardsticks with divisions set up for dividing by 3, 5, 7 etc. but you could do that with a meter the same way.
The argument was that imperial was better because you could do an exact division and get 6 and 25/48".
25 48ths is 33.333 repeating 64ths. You still have to eyeball a third of a division, the same way you would have had to eyeball half a millimeter.

Except I have several tape measures with 64ths, they aren't exactly uncommon and you can do 48ths with 64ths

you don't have to eyeball it as much though
