At that point you could just generalise it to "in case of emergency". Being able to access your stuff while you're in a coma for three months is a similar situation but one might not want to or be allowed to open the oppressive dictatorship file you mentioned. Also, it strikes me as an odd thing to prepare for. You planning on visiting North Korea, or are involved in things that look very illegal but are secretly actually fine and it would take months to talk your way to a point where you can communicate with your loved ones?!
