  Experimental measurements point at the Standard Model (SM) as the theory of
electroweak symmetry breaking, but as we close in on our characterization the
question arises of what limits in theory space lead to the SM. The class of
theories with this property cannot be ruled out, only constrained to an ever
smaller neighbourhood of the SM. In contrast, which class of theories do not
posses this limit and can therefore potentially be ruled out experimentally? In
this work we study both classes and find evidence to support the Standard Model
Effective field theory being the single road to the Standard Model, theories
that fall outside this class keeping a `minimum distance' from the SM
characterized by a cut-off of at most $ 4\pi v/g_{\rm SM}$.
