The privatization of California’s electric grid, and deregulation of Texas’, have proved this to the point of not even being debatable anymore. Laissez-faire advocates baffle me, as there are so few empirical counter examples that support their theories.

Duh ?

Governments are really good at operating public goods and natural monopolies.

The idea that privatised public transport, water, electricity, health care, education, public housing, prisons etc are better than publicly run alternatives is as laughable as having private fire departments.
