Maybe it's me but I have noticed a common theme with people on your side(I apologize for the expression it's not meant badly), you seem to ignore a crucial part of trade which are goods, services, knowledge and workers. You can't and shouldn't expand free trade forever simply because of structural and sometimes legal inequalities, for example the EU already made the mistake to put countries with high work cost in competition with countries with low work cost within the same region, it could be fine if the EU was an actual federation and Brussels was in a position to actually have an influence on territory development but the EU isn't a federation.
What I'm saying is that when you expand free trade to countries with either lower standards or lower structural costs, the only way is the pauperisation of your own standards, for workers it's unemployment or lowered wages or lowered workplace safety and for the consumer generally lowered quality.
