They're currently selling Teslas in NJ (without a middleman) and not having any legal problems because of it, so your example's premise seems to be flawed.
I can understand what you mean, but to the end consumer they are going from being able to buy a Tesla directly to not being able to.
Shouldn't have been issued according to who? According to law, it should've been issued, otherwise you don't need a law change to revoke it.
Recently they were told differently: that the executive has made the decision, and they're shut down. Not much wonder that Elon's unhappy with the situation. Nobody likes the rug removed from under their feet. Plus it feels like (and probably is) inside ball when something like that happens.
