That doesn't following from my way of looking at it. Your view as I understand it: research shows that availability doesn't change dietary habits over the short term, therefore something other than availability is the fundamental problem. My view: the research you've linked shows that availability doesn't change dietary habits over the short term, but that might still mean that availability is a fundamental problem over the longer term or still a necessary but not sufficient fundamental problem over the short term (e.g. maybe it takes availability + education).
