Perhaps "existence" itself comes in different varieties, where:

• Some beings exist only as relations rather than as individuals.
• Some entities can switch between different existential states.
• Some forms of being are temporary configurations of a larger ontological structure.

LessWrong readers concerned with existential risks should certainly care, as frameworks of this nature send dangerously mixed signals about acceptable behavior in high-stakes conflicts. Similar views have grown increasingly influential in global policy contexts. Leaving states uncertain about how their actions will be interpreted or responded to encourages brinkmanship and destabilizes diplomacy and deterrence strategies. Existing crisis management protocols are already fragile, and the last thing you want to do is to add more uncertainty and lack of consistency to the mix, especially when nuclear-armed states are concerned.
