Yes, since Uwe mentioned Peano, that's why I pointed out that
Peano doesn't care (you have to get to algebra, i.e. "up" in
the conventional foundational ladder) for 0 to have a special
role.

About the cultural thing... you seem to be a zero-counter (as
I am, too): there, too, I think that "our" position isn't in
any way "better" -- some theorems look better this way, some
that way; some inductions are easier to start at 1, some at
0.
