I don't think anyone has questioned the importance of *gradual* transition from one person to another in Parfit's argument. After all, we have discontinuities in consciousness all the time: when we are asleep, if we perform some action in a drunken stupor and later forget that it ever happened, following a head injury which may result in the excision of entire chunks of our lives from memory. Given this, we can imagine changing from one person to another despite discontinuities.
