Less snidely, ignoring the context in which actions take place is not reasonable. We are immensely shaped by the environment that we are a part of.
The trickier question of how to balance such realizations with the concept of individual responsibility? It seems the jury is still out on that one. My guess is that the most productive efforts will be those that produce better outcomes from a systemic perspective, through more harmonious alignment of underlying incentives and a developing understanding of human nature.

I'm an old fogey who isn't young or cool enough to have all my eggs in that basket. My eggs are far more in the sitting-around-reading-books-and-newspapers and hiking-in-the-mountains baskets.
But I do think this hysteria is pretty overblown, as your comment demonstrates.
