For example, we could represent the real numbers "base pi" if we chose

However, if we chose to represent the reals that way, we would have to
change the usual algorithm for multiplying; because clearly pi*pi is
not pi! (i.e., 1.0000...*1.000... should not equal 1.00...!).

No, that's incorrect. In base pi, the number 1.000(pi) is 1. The
number 10(pi) is pi. So 1(pi) x 1(pi) = 1(pi) = 1 x pi^0 = 1, as
expected. 10(pi) x 10(pi) = 100(pi) = pi^2, also as expected.

Is "I was channeling Homer Simpson" a valid excuse?

You are quite correct. b^0 = 1 for /any/ base.
