The EU does not allow member countries to negotiate trade deals privately. All trade deals must go through the EU, which means any trade deals applies to all EU countries. It's an all or nothing thing. So even though Poland might want to allow free trade with the UK, they simply cannot do it. It must go through the EU, and the EU has said very strongly that they will not allow it. Free trade means free movement. No exceptions. Once you understand that, the Brexit is just even stupid to consider.
