The majority seems too trusting that the government will appeal its losses.
Strategically, the government could enact a policy affecting a million people, be sued, lose, provide relief to the named plaintiffs, and then not appeal the decision. The upper courts never get the opportunity to make binding precedent, the lower courts do not get to extend relief to non-plaintiffs, and the government gets to enforce its illegal policies on the vast majority of people who did not (likely could not) sue.
