What can the government ever do? 1) Generally, do nothing and so cause no harm. 2) Specifically, subsidize a particular business, and so do harm that is beneficial to said business. 3) Regulate natural monopolies.

(viz, prevent toxic waste dumping, radio wave jamming, etc.) Only #2 is a serious vote getter.
