The passage around this formula

…reproduces a quantity the field already measures by an independent route, not new physics. Inverting the formula returns mopm_{\rm op}[LG\mathcal L_{\rm G}]=ℏ\hbarΦ\Phi/(vrv_rb)=m exactly, because the phase was defined from m in the first place. That circularity is the point of this section: it isolates what an idealized, confound-free evaluation looks like, so the next two sections can show exactly what breaks the idealization.
