His analogy is perfectly consistent. There are laws prohibiting minors from purchasing alchoholic drinks. In the same way, porn can be restricted from minors. He is just saying that there needs to be strict enforcement of a law against porn to protect minors.

I guess your argument is that there is no need for a law against alchoholic drinks since there is common sense to not give alchohol to minors and for minors to not drink alchohol.

But the existence of laws regulating alchoholic drinks purchase suggests that common sense is not enough and laws need to be created for it.
