So it's more of an opinion than an argument then since it's based on entirely subjective "facts".
I would count as an intrinsic value the sheer size of the EU's internal market, the power of its politicians by merit of the population and market size they represent and everything that is related. In a world that is somewhat defined by corporations that become bigger and more powerful than governments and therefore start to overrule governments, potentially even take over their functions, I find this to be a very important intrinsic value.
Add to this the advantages of centralizing certain government functions that can actually help economic growth, government efficiency and save you taxes on top. I've never heard anyone say that huge corporations could offer their services cheaper if they were just a lot of independent small workshops, but somehow people assume that to be true for governments.
