I think it makes even more sense when written in terms of tau.

    e ^ (i * tau) = 1
In plain English: “rotating by a full turn is the same as doing nothing”.

this, and the unit circle are by far the most compelling arguments for tau.

Euler's identity isn't some mysterious thing where all these mathematical building blocks meet, its a completely straight forward and fundamental consequence of circles existing!.

2pi is a full turn. Using a different name doesn't change much.
