> If you steal an candy bar, the government can "compel speech" in the form of forcing you to return the stolen property.
This is a great example of a thing that is not remotely 'compelled speech.' Here's the wiki article on the topic[1]. There's a pretty high bar for the government to create exceptions to the First Amendment.
A better example of compelled speech is the FBI trying to require Apple to write software that would give police a backdoor into any iPhone user's phone[2].
