Largeness of the wild locus

We show that the wild locus of an étale morphism of smooth adic spaces over an affinoid field is either empty or contains a divisorial point. As a consequence, we establish the equivalence of curve tameness and valuation tameness without using resolution of singularities. Moreover, given a finite étale map of regular schemes $f\text{\hspace{0.17em}⁣}:Y\to X$ that is curve tame over a base $S$, we construct a compactification $\bar{f}\text{\hspace{0.17em}⁣}:\bar{Y}\to \bar{X}$ over $S$ that is numerically tame.
