That's a great point but the truth is that we already treat human lives as a resource to be spent: for instance, we allow planes to fly and automobiles to be driven even though their safety is not perfect. We allow that, out of say a million flights, one plane will fatally crash killing usually everybody on board (I don't know what the real number is- I made the 1/1mil up).
So basically we accept that in order for each of us to fly to our destination, 300 ish people must die every so often. Like a kind of sacrifice.
I don't see how any of this is going to stop any time soon, especially when people are always quick to tell you how safe flying is, or how, although road accidents are common and people get killed in them, "what can you do, stop driving?". It seems to me that at some level we all accept that in order for us to have our fast transport, some people must die.
