all measurement systems are arbitrary. people can only say the meter is objectively based on the speed of light because the distance its distance was converted to that more objective measurement in 2019 which is why it's the unsatisfying number of the speed light travels in a vacuum in 1/299,792,458 of a second instead of something like an even 1/300,000,000 or even better 1/1,000,000,000 a nanosecond.
