Maybe. But private companies own the poles and transmission grids in many countries. You don’t see these problems in the U.K., Spain, etc. (Or for that matter in Maryland, New York, or Illinois.)

People calling for nationalization are focusing on the wrong thing. For the reasons you mention, utilities need regulation. Both government ownership and rate regulated private monopolies are a model that works routinely around the world. The ownership structure therefore can’t be the reason for PG&E’s problems. The problem instead seems to be California. PG&E was heavily regulated by the CPUC the whole time. What was CPUC doing wrong that the regulators in Germany, Spain, not to mention other US states are doing right? Bigger picture, why is it California that seems to suffer from all of these problems? Among the worst schools in the country. Housing prices out of control. Massive failed investments in public infrastructure? Cities running out of water?
