I was surprised to see BOA list "It's finite" as an advantage. It seems like this mentality is all anti-inflation (which seems justifiable) yet the alternative is taking a wildly experimental approach to savings. BTC hasn't proven stability within a month really yet, why trust it for 50 years? And then if you put in that 1 day's wage of Bitcoins, what happens when the market cap for BTC fluctuates? It won't always be in a steady demand, it will depend a bit on how many people are using it, no?
I am a doomsdayer also I think that it can only succeed if it always remains the same price or keeps going up, but the belief that this is possible is obviously intellectually malformed.
