There is a reason they are ignoring it. Their notions of value aren't workable or coherent. If I manufacture a gun and it is used by a rancher it reduces predator-on-livestock losses. If I manufacture it and an eventual buyer uses it in a school shooting it causes large losses. There is this weirdly persistent leftist idea of demanding absolute precognition with values for things which are determined in the future and utterly irrelevant and unknown. If I buy coffee beans from locals of Cape Horn growers for my use at the local prices I am helping by supporting local farmers. If I roast them and sell them overseas for 100x the cost I am somehow harming them now. The Marxist derived notions of value and exploitation are downright certifiably insane.
