Okay - am awake now but probably will have to lock this again soon as unfortunately I have some IRL stuff to deal with today.
I read elsewhere about questioning how correct the analysis about Satoshi's stash is and of course it is going to always be open to a fair amount of uncertainty.
I think simply the fact that there are so many coins from 2009 that haven't moved is what tends to lead people to believe they were only mined by Satoshi (and many believe that Satoshi was not one person and that Hal Finney could well have been a part of the group).
Certainly I accept that this cannot be proven - so the point of this topic is to discuss whether or not this would be a likely concern for governments (not to try and answer the unanswerable question as to how big Satoshi's stash actually is or whether he/she/they still have control over those private keys).
governments dont and wont care.
just like they dont care about the gold in the ocean or the gold lost in some amazon rainforest that has the slightest chance of appearing one day.
but putting aside the number of people debate
(day1: satoshi, hal, |)ruid were atleast 3 people. then in the first 2 weeks there were atleast 9 people.) and just classing it as a large clump of many wallets.
again the debate about the large clump doesnt matter either. and it actually adds value to the coins that are in circulation. because although there are 14mill mined.. there are only 12-13mill in circulation.
governments would be more worried about blockstream changing the reward sceme to allow more than the 21m bitcoin cap
and even if the early miners do pop back up or someone brute forces the addresses (yes ciyam i know the odds) then the price change is just temporary drama which gives opportunity for a nice cheap coin buy up.. so again not negative. just like treasure hunters raiding the oceans or rainforests. it all ends up as positives in the long term
