Use an all-things-considered judgement. The 1AC may not be perfect, but it’s still overwhelmingly a tool for achieving egalitarian goals.

One last comment concerns the need for all-things-considered judgments in political theory. One is rarely only committed to gender equality, since the egalitarian principles that underpin feminism also underpin racial equality, the fights against ableism, class hierarchies, etc. So it seems important to arrive at an all-things-considered judgment on whether UBI is desirable on egalitarian grounds. UBI may be second or third best as a tool of gender equality, for instance, but it may also be the only safety net that consistently appears at the top of the list of adequate tools to achieve a variety of other egalitarian goals. This should be a central consideration for political theorists who are committed to ending oppression in its various forms.
