I’m curious what the purpose is here, since I don’t see it explained on the linked page. Are they essentially trying to bait the state into issuing fines so they can challenge these laws in court? Or just demonstrate how dumb the laws are?

Civil disobedience in this way (buying or owning an “illegal” product) doesn’t seem like it would have the same impact as a sit-in against segregation or something like marching on a highway. There’s nothing really visible for media to show off, and no real inconvenience to anyone. The state could just ignore these entirely, right?
