All that link does is show why it was better to be in the EU than out. You can complain about how we won't have any control over the customs union now but if we were in the EU we would still have the right to veto any proposals given forward by Brussels. I say this acknowledging the system is fucked within the EU but we were in a stronger position to try and change things from within than out.
Never going understand how you can be so strong about just wanting to leave with no deal. And I'm sure you'll not even try to put a reasonable argument forward.
Down with this sort of thing.
