Staying in the EU to most rank and file Pro Stayers only means open borders, to travel through Europe freely without constraint. The reality is now coming out, the real stayers are vested interest, the civil service and the Righteous Left.
Staying in the EU will be the total destruction of Britain as a independent Nation, there will be No border control, no sovereignty and completely dictated to by Brussels. Its Banking system will be transferred to Brussels and the Pound will go, Britain will just become a Island State of the EU, flooded with the flotsam of the world, as refugees and country shoppers enter Europe they will have total free access to Britain. The British People do not want this.
