interesting, I do think this could be a bit of a problem for people holding large quantitys of btc, but otherwise for most people with about 1-10 btc this would not be much of a problem (as long as they do not want to instantly withdraw all in one go), I would simply assume that you would probably only withdraw as much as you need ($0.5k-10k)for a (rather expensive) holiday.

Depends on where you want to go for a holiday though
