The benefits outlined in the argument are only valid if the political aspect of the EU functions efficiently. The EU’s undemocratic nature and unnecessary bureaucracy create uncertainty about whether the EU will even exist in the long-term. Adding to that the growing resentment to the EU in several Member States and looming referenda, the EU is an unstable entity.  A trade bloc, on the other hand, is not conflated with issues regarding sovereignty, national identity, immigration and other sensitive political issues. Therefore, it is likely to be considered safer by potential trading partners. When the EU is not a political agreement, foreign investors can have more trust that the countries involved now will remain involved in the future.
