Using that argument, you could say that every mathematical operation can boil down to addition and subtraction, because multiplication, exponentiation, and division are just flavors of those two operators. However, they're really convenient and I think that if an operator adds enough convenience it's worth the overhead of a new operator. You can argue that the new bind operator isn't so convenient compared to the .bind syntax, but your argument is a bit weak.
