No, it's because our civil service did no planning for this (in fact were explicitly not allowed to), have no infrastructure or skilled employees to negotiate it, and are fighting a constant battle of trying to inject the economic reality of Brexit into the heads of our MPs who refuse to hear it for political reasons. You can be for or against Brexit but if the rulers are pretending that it's not going to hurt if we lose trade access then we are in big trouble.
