Tunneling is indeed expensive, if that is how this will be build. Given that the footprint of such a system likely will be relatively small it might just be build in the same way we build other underground infrastructure of a similar size. Or do you think they also didn't bother building sewers in Swiss cities and towns and are still all using outhouses? > When the guys sitting on piles of nazi gold and the money from dead foreign despots say "nah fam, that shit's too expensive", there's no way anyone else could afford it. lol, that's one hell of a top tier hyperbolic stereotyping trope supported "argument".
