Porn and the Law of Unintended Consequences

So a California Law requiring condom use would mean safer working environments for porn stars, right? Probably not. Four things will happen: some companies will go out of business, a lot of production will cross borders into Arizona and Nevada, some production will cross oceans to South America and Europe, and still more will move underground. The net effect on HIV infection will be a purely empirical matter, but we can say with certainty that the proposed legislation will probably make the industry more risky (and probably more depraved, on some margins), not less.
