Tesla is a large US company. Elon owns (less than?) 20% of it personally. They make cars in the US. I'll make Elon hurt by hurting Tesla is childish and counter-productive. Elon's not gonna care. So instead of protesting Tesla protest against the government.

Musk has power in part because he can pour enormous amounts of money into political races. A lot of that money is based on his Tesla and SpaceX holdings, so lower share prices directly reduce his ability to borrow against those shares.
