Have you even given thought to emergency infrastructure?
Clearly the purpose is never to help you in an actual emergnecy, but to stabalise day to day life by signifying and appearing to make concrete (reifing?) radical contingency.
It is always comforting to look at emergency infratructure with the realisation that we are not using it at that moment and therefore we assume that "at least it hasn't come to that".
I, in fact, have 2 such instances: an emergency bottle of alcohol in my desk (which is not for ever drinking but a gaurantor that things haven't hit rock bottom); and in the pantry at home we have an army produced instant meal which is the gaurantor that I have some domesticity left intact. Consuming either of these items would be nothing short of traumatic.
What other items act in this way, as empty signifiers to insulate us from the Real?
