Some punishment in public goods games is retributive justice-seeking, not cooperation enforcement.

Evidence

In a replication (see supplementary material of Johnson et al. 2009), participants also had the opportunity to pay in order to help others and the results were nearly identical. Participants who, in the random income game, reduced the income of high earners or increased that of low earners were more likely to punish low contributors in the PGG. These two studies are consistent with the fairness interpretation of punishment. At least some cases of punishment in PGGs are better explained in terms of retribution than in terms of support to cooperation. — Nicolas Baumard, A mutualistic approach to morality, 185
