Airlines are another one. Though it is less central planning but rather bailouts where they get involved.

The FAA is probably the best example. Could probably use some competition. Of course there would need to be some sort of governing body like Insurance and a standards body but those could be private and voluntary. If one didn't care you should be able to fly on a wild-cat airline IMO. I wouldn't do it but I can see people choosing to do so.

See socialism usually just removes choices for the masses and calls it organized. When they fail at doing their job they say they need more money. We see this over an over again.
