And all of the fractions in metric are just powers of 10: one tenth, one hundredth, one thousand. Powers of two are great when you're working in base 2. It's a big hassle when you're working in base 10.

Everyone also gravitates to length and how fractional powers of two are sensible. I'll grant that they're at least sensible although awkward in base 10. But what about every single other thing? For lengths greater than one inch, there's no consistent pattern. For volumes there's no pattern - mass, weight, etc. The thing is a monstrosity. People pick out one part that's halfway acceptable and act like that's a defense of the rest of the pile of garbage.
