Time can be non arbitrarily defined as a round number value of times cesium oscillates between two hyperfine states, to allow time to be non arbitrary and still a useful size.
Not arbitrary. Base 10 because we usually have 10 fingers and those are useful for learning counting. If you have to choose a base, 10 is a good option for humans.

The round number would still be arbitrary, no? It’s roundness would be based on the base 10 counting system, which is also arbitrary.

That’s still an arbitrary number to pick, and the choice of cesium oscillation seems pretty arbitrary in the grand scheme of things.
