I would've liked to see the Foundation continue. At the current moment in time though, I understand the wish to end it since there is no tested-to-work tech for the fair distribution (self-sovereign/decentralized ID, WOT, voting systems).. as well as the inability of our small community to launch the many centralized experiments we've discussed/planned/outlined to attract wider user base
Option 3 I dislike, since there are a bunch of coins in lost privkeys (and possibly in questionable entities possession; case Cryptsy) -> Drags out the "full supply" of coins available for circulation.
