The assumption that Europeans can just absorb high energy prices is crazy. Ought to be a national imperative to invest in infrastructure to lower prices.
Lol. Depending on the country and who the buyer is, 50-80% of energy prices are taxes and levies. Those prices have nothing to do with missing infrastructure.
The problem there is the "national imperative" part imho. All EU politicians are hell-bent on ignoring any kind of market-based solutions, doing everything through regulations and picking winners. So there will never be a proper market equilibrium and therefore prices will always be higher than in places without all those regulatory interventions.
Investment won't help there in any way, because if that investment were worth it, it would already happen because of market forces. If it doesn't happen on its own, then the state (doesn't matter which level) has to do it, which means using tax money, which means that prices will rise. So that state investment will further skew the market equilibrium, putting the EU further behind.
