That's not a "potentially more plausible" way for it to fail. It's merely a theoretical vulnerability. The bursting of a bubble in the price of a worthless asset, though -- that's, historically-speaking, a dead certainty. Come on, people. This isn't the first asset bubble in history (though it may be the most cleverly-designed). We all know how it ends. People keep paying ever-higher prices for the asset, hoping it will go up. And it does for a while. Then one day, the price of the asset stops going up, people realise they don't want to own this asset now it's stopped going up, the value collapses, ka-pow, it returns to a more natural value. For a real estate bubble, this may mean a halving in prices, because the natural value of real estate is quite high. For bitcoins, the natural value is zero.
