A legislature is thwarted when a judge refuses to apply its handiwork to an
unforeseen situation that is encompassed by the statute's aim but is not a
good fit with its text. Ignoring the limitations of foresight, and also the
fact that a statute is a collective product that often leaves many
questions of interpretation to be answered by the courts because the
legislators cannot agree on the answers, the textual originalist demands
that the legislature think through myriad hypothetical scenarios and
provide for all of them explicitly rather than rely on courts to be
sensible. In this way, textualism hobbles legislation -- and thereby tilts
toward "small government" and away from "big government," which in modern
America is a conservative preference.
