This is a lot to absorb.
But my question is, when did they threaten to demolish the tunnel?
SHA3 (keccak)
Luke JR (the protagonist) wanted to drop the hashrate
other stuff luke suggesting moving over to sha 3 to render ASICs(mining) useless
Wouldn't it be more correct that they said widening the tunnel will cause a collapse and destroy the security of the rail?
So a soft rail needs to be created to protect the first rail from such a failure.
analogy is more like instead of the whole public rail engineers (ALL engineers paid or not) work together.. but secondrail just want a second track by using multiple threats and to leave the town with just independent metal workers to reinforce the tunnel.. basically scaring people to say it will collapse without "the big team"
basically blackmail
