I think that's a great question and to me it gets down to, 'What are the negative consequences or externalities created by breaking the rule(s)?' With a mining company non-compliance could poison water supplies and sicken/kill people. With Uber (and a lot of the sharing companies) they can cheat workers out of the protections they would normally receive with a job. On the other side with Tesla, selling directly to consumers doesn't hurt consumers at all, but it does create a slightly uneven playing field with incumbent manufacturers who have to sell through dealerships. With Uber, customers tend to get a better service but it creates an unfair playing field with taxi companies, who have to pay an enormous amount of money for medallions while adhering to tightly regulated fares. From the government's standpoint, there's usually some amount of discretion in enforcement of the law. Laws that protect people from harm should be pursued more vigorously than laws that maybe protect old business models more than they protect actual consumers.
