I think what I'd tell her, honestly, is that it really sucks that our legal system has no way to challenge bad laws in court without getting arrested for them first, and we should fix that. It shouldn't have required her getting arrested to have a court case of the form "If she does this, she's clearly going to get arrested, let's have a judge review that law." And it really sucks that it wasn't her case that decided that the Montgomery bus discrimination laws were unconstitutional, it was the cases of Claudette Colvin and four others (Browder v. Gayle), and really at most one ought to be enough.

(And, in turn, if a judge reviews the lockdown order and finds that in fact it is a legitimate exercise of government power, then we're in a very different situation from the one she was in.)

Rosa Parks and a billionaire defying an order to put production on hold because the county feels it isn't safe for his workers to return to work makes for a hell of a comparison.

that I'd never insult her by comparing her to an electric car corporation

Note that enforcing the law was crucial to Rosa Parks achieving her aims. Had the officer said "it's a stupid law and I won't enforce it", it would have foiled the test case that was planned with the aim of overthrowing the law. She's a poor example of your point.

Rosa Parks, the woman who was falsely arrested while committing no crime?

Which features of Rosa Park's successful fight for civil rights do you feel map on to a misguided attempt by the billionaire scion of a pre-apartheid South African mining family to send his employees back to work during a global pandemic?
