First of all, the proposed design is estimated to cost 21 billion EUR. Secondly condensed matter and quantum information already get plenty of money: superconductivity alone is a market worth around 5 billion dollars, google is spending billions of its own money into quantum computers. But sure, lets give these starving fields that produce commercial products a some tax-payer dollars at the slight cost of completely de funding high energy physics, I'm sure that will get the scientist there to care about the proton despite them very consciously choosing to do something else.
