this is, imo, problematic for BTC holders in #2 and #3. the realization that BTC value units now have the potential to "leak" from what's supposed to be a self contained firewalled off system will destroy Bitcoins Sound Money function. right now, i could buy gold and throw it in a safe and never access it for the rest of my life and, in the absence of the Bitcoin alternative, be confident that it would retain its value. in your demonstrated scenarios above, i could NEVER count on that. therefore, the natural conclusion is that Bitcoin would NOT be Sound Money.
That is true only considering that the the "peg" is broken.
Peter himself has suggested this is
not a realistic scenario.
As long as the peg is working then yes you can absolutely forget about your BTC and if, once you come back to them, the network has decided on using a different then you will be able to claim your 1:1 stake as everyone was.
