It’s the definition of arbitrary. There’s no reason to pick those specific things to base your system on. They picked them because they’re easy to measure and have a reasonably consistent value over time. Then they divide it by some number that makes it useful on a human scale. There’s nothing fundamental that lead to those values being chosen. They were just useful. Nature doesn’t work on meters. It does work on the speed of light. It is a fundamental unit of nature (excluding the unit of time, which is obviously not fundamental, but we could use any measure of time).
