It's not unsubstantiated. The federalism is a well known expensive hindrace for any progress. Everyone doing their own shit also means everyone has to fight it out with everyone on how they work together. There are good reasons for this, but the price is also obvious.

Thinking the number of federal states is equivalent with an efficiency factor is utterly unsubstantiated. There may be a correlation (or not, I don't claim anything here), but `efficiency_gain == federal states before / federal states after` is pure fantasy.
