Ebay? A friend to ship it? I agree on the de-google part but putting graphene on a used pixel is aligned!

Absolutely, and it is irrational to refuse to buy hardware from Google (which, with Graphene, is under your control) when the alternative is to either run a Google OS on a third party phone (and give up control of the software), or Apple (equally bad), or some impractical and less secure alternative like a Linux phone incompatible with Android apps.
