How is that not an equally arbitrary explanation?

  Because we observe directly that many of our humans are distressingly vulgar, and seem to enjoy it. We do not observe, directly or indirectly, "innate brain wiring to always create taboo swear words". Of course, that leaves unexplained why many (all?) humans enjoy being vulgar...

    Because we are not rule-machines, and we enjoy breaking the rules, including "social decorum" and "taboo" from time to time? That's also how comedy works, even without using any vulgar words.

  It's not even an explanation, it's a tautology: vulgar people are vulgar.
