[Dragonball]why did Vageta let Bulma cut Trunk's tail off sometime between birth and the Android Saga, in Saiyan culture that's almost analogous to castration?

Because after his long stint on Earth he learned that the tail wasn't the source of a Saiyain's strength it was a crutch, and in fact their biggest most easily exploited weakness.

He also didn't care much for Trunks since he didn't even look Saiyain from the get go, so it was a lot easier for him to let go of any potential traditions.
