"A soft border+hard Brexit would turn most of the UK's economy into smuggling operations, moving any goods into Europe."
And what used to happen with the border? Smuggling. Hard to stop too since there isnt a land border but an artificial line. Interestingly since the EU have accepted the UK would have a competitive advantage for leaving I expect Ireland would be very prosperous for having the protectionist subsidy of the EU for being in and the freedom from EU bureaucracy being out. But you are right that the EU cannot have a protectionist bubble with a hole. Again their problem.
