The EU wants more of our money. It wants to send us more of its unemployed. It wants to continue its huge trade surplus. All this puts it in a weak position as we leave.
So it invents silly ideas. It says the ECJ will continue ruling us after we have gone. This does not apply to any other independent country and should not apply to us. No need to pay to remove it!
It says it will stop UK citizens legally settled in one EU country moving to another after we have left. Fine. We cant stop them doing that if they want to. I doubt UK pensioners who have bought villas in Spain or Portugal will want to move to Poland or Germany anyway.Again, no need to pay for that.
They would be foolish to demand we pay to export to them, as that would be illegal under WTO rules. The only legal way to pay to trade is recognised tariffs, where their exports would then gift us a £12 bn tariff revenue to give back as tax cuts.
