You keep ignoring the fact that leaving 100s of stakes open forever means that there is good chance someone with access to BTT server will have power to steal these stakes and kill/crash nem completely. How is that crypto? The fate of unclaimed stakes must be decided before the distribution.
That is the first good argument I have heard for having a time limit on claiming the stakes. One month is still too short we need to give people more time ...
EDIT: Although I don't think there is a good chance that would happen.
Why don't you think there is a not good chance that will happen? All BTT messages are archived on some hard drive. The BTT owner can already do that, so can everyone with access to that machine, not just now but someday in future one or two year from now. How are you putting the entire fate of nem in the hands of people you don't know? Why the heck anyone should buy nem when it's fate is totally insecure with future influx of "billion" nem from unknown people?
I don't care how long you want that wait to continue. Nem should not launch until this issue is settled.
