I think you misunderstand the history of the EU project: its goal is what you describe, but it must be balanced with respecting the autonomy of each individual nation inside the union. It can only work if all involved governments agree to do it. Which is an incredibly difficult thing to achieve.

What we have now is the progress we have managed to make so far. If it does not appear like much, well, you should have seen what things were like before the EU, especially regarding red tape.
