There was no reasoned argument from either side. That's why people, just as on this forum, debated the issue amongst themselves. The numbers quoted by both sides were designed for effect, but the simple truth is that there is only a finite pot of money to disburse, which means that not everybody can have what they want. And as for business, it will adapt to whatever situation it is confronted with. That's what they do, otherwise they go under. Consequently I believe that with the prospect of this issue hurting both the remaining EU members and the UK, a sensible agreement will be forged. The main side issue for the EU not addressed by Brexit is the ongoing fully centralised power agenda of the EU commission, but that is moving relentlessly forward irrespective of the wishes of any member state - you can do that when there is no control mechanism. Divide and rule. Allowing some national controls divides the constituent states. Formulating and handing down legislation by an unelected commission is the rule bit.
