Are you telling me that Sweden, a country of 10 million people, which has wildly differing electricity prices within that same small country¹, could simply use copper conductors to solve this problem, but chooses not to for political reasons?
Yup.
Might not even be wrong to have made this choice, I can't tell — economics (which is an important part of politics) is outside my domain.
What possible political reasons might those be?
If I had to guess — and it would be a guess, I'm a software engineer not an economist or a politician — I'd just give the usual catch-phrases that seem to cover everything in politics: is it popular? How much would it cost and what else can we spend that money on? Will this be finished in my term? How likely is the situation which makes this useful (without the benefit of hindsight)?
Men även med så intetsägande och generiska uttalanden betyder det faktum att jag inte kan någonting om svensk politik att jag kanske saknar något som någon svensk väljare skulle anse som "sunt förnuft".
