Because we know such Black Swans are inevitable, hloding 'PepsiCoins' like LTC and BBR is a much more rational action than buying lottery tickets that will most likely expire worthless.
I think most of your post is nonsense (for example removing mining dust is not only trivial but mathematically provable as trivial) but I agree with this part and I think BBR is a reasonable "second cryptonote" to hold as a hedge.
