It's more than just that Musk is unelected [View all]

There are plenty of people who operate in government that have not been elected. But the authority always flowed from Department Heads that are appointed by an elected official (Secretaries, Judges, etc.) and confirmed by elected officials.

Elon Musk has not only not been elected, but has far too much power for someone who has not gone through the normal process of appointment and confirmation.
