I hear where you're coming from but can you really imagine it ending up being as simple as that or the EU permitting it to be so, it would make a complete mockery of the Schengen zone and amount to freedom of movement but in one direction only.
How it's to be contolled or policed is yet to be explained but I think you can safely guarantee that there will checks somewhere be they at the point of departing UK, arrival in Ireland (Northern or the Republic), or en route.
It's bound to be a dogs breakfast though and for good reason something deliberately swept under the carpet by 'Bojo the mendacious'
