The network is not secured if you just offload the externality to the international electrical grid. You just traded one tgreat model for another, and boy it is a doozy.
Not sure I understand your argument, because there are externalities the network is not secured? All consumption of power created by fossil fuels has negative externalities. Also, there's no requirement that miners are on the grid (lots of mining operations use off-grid excess power that cannot be stored).
