why oh why are these silly ideas even part of the bitcoin discussion
oh wait

phase one
make it hostile and inhabitable to live in the bitcoin network. get people to lock up/abandon coins on the bitcoin network and displace people into other networks long term

phase two
claim the coins left behind

wait this sounds familiar
nazi germany: hmm these polish have abandoned their antiquities, i guess they can be taken now
or
banks tell people to lock up gold for centuries and play with bank notes.. later take the gold no one reclaimed because their descendants are to busy playing with bank notes..

reality. even decades later many countries are trying to get their assets back from nazi thefts, but its harder to get property back after its stolen and moved on..

understand yet

taking coins has nothing to do with energy. its called taking coins for a reason. it involves taking coins without the signatory's consent
