He compared Elon Musk with John Galt – the fictional character created by Ayn Rand in her novel Atlas Shrugged, which was about capitalism. Not crony capitalism. More finely,  rent-seeking masquerading as capitalism. The leveraging of government force to get rich. The redistribution of – as opposed to the creation of – wealth.

What are carbon credits?

They are a wealth redistribution scheme. Company A produces something of value for which there is a market, established by the fact that people are willing to exchange their money for it. Like a truck with a V8 engine (or a car with a V6 engine). But the government says these things produce more "carbon" than it says is allowable – according to an arbitrary standard it lays down based on assertions that "carbon" is causing the "climate" to "change."

The government – more finely, the regulatory bureaucracy – says this excess "emitting" of "carbon" must be cancelled out via either the production of vehicles that "emit" no "carbon" at all – at the tailpipe – for which there is no (or very little market) or via the purchase of credits from another producer of such vehicles in lieu of producing them.

Obviously, none of this form of exchange is voluntary.

That is how Tesla – which is Elon Musk's electric vehicle operation – funded itself, in the manner of a tick feasting on the blood of a dog. The "carbon credit" being a kind of transfer tax imposed by the government but collected by a for-profit corporation. It is how Tesla sucked dry the once-successful Chrysler, Dodge, Ram and Jeep brands that are now rustling shells of their former selves. When you bought a V8 Ram or Charger or Chrysler 300, part of what you paid – assuming you could afford to – went to Tesla and thus to Musk.
