Apple's profit margins may be high enough to cover external costs, but is Apple fully compensating rare-earth mining communities in developing countries for the environmental effects of sourcing iPhone materials? Is Apple helping communities deal with mountains of disposed Apple-brand electronics? I imagine not, or at least not fully. The government would have to assess a tax or fee that covers those externalities, and then Apple would be forced to deal with it. Either pass the tax to consumers to save the profit margin, or control externalities to remove the tax at the cost of profit margin. Presently, Apple products, like all electronic products (and indeed, most products of any kind), are priced without regard to external costs. That the profit margins may high enough to pay for these external costs is only a coincidence due to Apple's silly-high prices.
