I didn’t compare it to metric though. and yes all your examples are stupid. I just said stone is my favorite because it feels so out of place for me.

you got the foot-yard backwards but at least 3 is a factor of 12. also inch, foot and yard, while impractical in ratios, are somewhat helpful lengths. like you can easily visualize an inch or foot, probably better than a mm or cm.

the pint/gallon was probably backward standardized, in that they were probably measures used for various drinks or cargo and named for those and got roughly standardized with 8x or 3x feeling appropriate. but stone just… exists it feels like. for no practical reason.
