There will always be a point in time when someone wants to effectively', 'retrieve their STEEM, power down and take it out'. Maybe these people feel that their time is over but they hang around because its hard to completely disconnect with the community.
I know I will power it down someday, but will I completely leave, who knows?
Indeed, it's hard to find another such a great community as we have here on Steemit. I tried:)
