What I meant was that the common situation whereby a person both (i) believes in persisting subjective identity (sameness of Cartesian Theater over time) and (ii) attaches massive importance to it (e.g. using words like 'death' to refer to its extinction), doesn't obviously or frequently give rise to irrational decision-making until we start talking about things like cryonics, teleportation and cloning.

I apologise for the unclarity of my final sentence if you took me to be saying something stronger.
