This existed before, just only for the wealthy. If Bob had that money in a Swiss private bank or distributed over a sprawling network of shell companies in the Carribean, it would be just as tough to get to. Or for the less wealthy; Bob could have put it all in cash in some hole in the ground that he won't tell the location of. Realistically that's probably more stable of a value store than bitcoin; it's possible that it all gets stolen but given a good location and storage, much less likely than bitcoin dropping 70%. This has physical downsides the aforementioned options lack, hence the real options so far only having been for the wealthy.
