Was that actually his claim or was he saying that it doesn’t necessarily reduce the frequency at which people do it? Clearly the frequency of drug use has gone up since they were made illegal. Now perhaps it would have gone up faster if drug use had not been made illegal but that’s rather hard to demonstrate. It’s at least plausible that some of the popularity of drugs stems from their illegality as it makes them a more effective symbol of rebellion against authority for teenagers seeking to signal rebelliousness.
Claiming that criminalizing can’t possibly reduce the frequency at which people do something would be a pretty ridiculous claim. Claiming that it hasn’t in fact done so for drugs is quite defensible.
In the real world, PhilGoetz’s interlocutor was almost certainly not making the sophisticated point that in some scenarios making X illegal makes it more desirable in a way that outweighs the (perhaps low) extra costs of doing X. If the person had been making this point, it would be very hard to mistake them for the kind of person PhilGoetz describes.
