I found this somewhat enlightening. It appears the principle barrier to sanity on this topic comes from electrical utilities. They seem to view these common-sense precautions as inconvenient.
Free nations such as ours fail when everyone starts thinking primarily of their own narrow, parochial interests, and fail to integrate themselves into objectively higher goods. These executives, and their lobbyists, have no reason to suspect they will fare significantly better than the rest of us if their obstructionism serves, finally, the cause of societal collapse. Their efforts are, to put it more kindly than the case warrants, short-sighted.
