The Arrow theorem is a pure artifact of single elections, where you cannot convey “preference intensity”. If you vote many times, you have vote trading, and you can create power sharing arrangements.

And in the last weeks I have found that a group in ETH Zurich is moving from theory to applications:

So it is time to move from Arrow to Casella, and from ordinal preferences to normalized utility.
