> The only sensible way to make the comparison is by total market cap
From the perspective of smugglers and their stuff, that's about the worst possible comparison.
So much so that yours is literally the first time ever that I've heard anyone even suggest market cap for a smuggled substance; looking at the definition of that term, I don't think that term is, or even could be by analogy, meaningful in this context.
It's always money per mass, £$€ per imperial or metric, never anything else.
