So my question is this, then: are there ways of meeting demands and distributing goods that a) price in externalities b) are not centally-planned? Anarcho-capitalists will tell you that by privatizing everything, you eliminate externalities. But taking their logic further, the only way to prevent pollution or climate change is essentially millions of people suing each other. I don't think I've heard many ideas that are quite as stupid. The thing is, I'm not a fan of markets and I'm not a fan central planning. I like the Marxian ideas of building/distributing things for-use (aka, at-cost as opposed to at market value), but then that still doesn't account for externalities. Even in a system where banking is socialized and allocations are made democratically, you still can't easily price in externalities. So what would a system look like that priced pollution, carbon output, and cost of disposal/recycling of each product into the product itself? The only thing I can think of is government regulation, but even that seems to work via disincentives vs incentives, so you're constantly having to police people to do the right thing. Is this the only way?
