In your example most (not all) libertarians would agree that you need some regulation of those corporations to prevent or minimize external costs, or in some other way factor them in. But the regulations should be as local as possible, and directed only toward the stated objective, with a little other government control as possible. E.g. you can tax my carbon emissions, but you can't regulate my vehicle or fuel consumption.

For example, regarding pollution, prohibiting any discharge of the offending pollutants, or measuring and taxing them in some way - but with no requirements about HOW a corporation should meet these regulations or otherwise run their business.

Unions are fine, and people should obviously be free to join them if they want. But there should not be any laws that require or favor unions, and government employees should not be allowed to unionize.

A government beholden to corporate interests doesn't matter much if the government doesn't have much power. But with power comes interests and influence, always.
