We will soon be living in an era in which we cannot guarantee survivability of any single point. However, we can still design systems in which system destruction requires the enemy to pay the price of destroying n of n stations. If n is made sufficiently large, it can be shown that highly survivable system structures can be built.
There is value in long years of obscurity, if one doesn't go insane or suicidal, in that, simply because nobody is looking, the habit of fooling around and trying things out gets ingrained.
