There's also the fact that people are expecting normality, IE not forced to eat canned foods/foods they don't actually enjoy. That will take some time to overcome for many people, who have enjoyed stability for so long. People will prioritise what they like first and foremost and coincidentally in the consumerist age, that is shared by the vast majority of people, not that everyone is so silly as to not start reprioritising, but there are a lot of entitled people in the country.
Nobody is going to jump over and fight over a can of beef, certainly not at the start.
