Bitcoin should be forked and Satoshi's 1 million Bitcoin destroyed completely, if he really owns that much.
A sudden withdrawal of of 1 million (or large gradual withdrawals) should be regarded as an attack on Bitcoin.
Or it should be frozen for now until developers are sure no one is going to withdraw the whole thing and crash the market.
Oh right, so you want to impose rules and regulations, terms and
conditions to owning bitcoin is it?
Ill bet you wouldnt mind storing millions of bitcoin and further
you would "withdraw" them at an oportune time that is beneficial
for your pocket.
