What the EU is trying to do has been done in the past and it has failed. The EU as it is right now is becoming the next Sovient Union. A undemocratic, centralised, bureaucratic superstate that strips the people from their sovereignty, independence, cultural and ethnic traditions.
Further, you seem to assume that without the EU, trade between countries would somehow radically decrease, i don't see that happening. The European Economic Area (EEA) and the Schengen treaty exist independently from the EU. Norway and Switzerland are not members of the EU, yet they trade perfectly fine with others. The EU is not necessary for free trade.
PS: Feel free to downvote, but at least make an argument.
