In having an email discussion/argument with Silas, he argued that, if the science behind anthropogenic global warming is correct, then the government capping total emissions would be no more objectionable than the government enforcing laws against murder.
Now, I myself have long thought that sure, the government does some horrible things that would NEVER occur in a free society, but some of its activities are closer than others. It's crazy when cops hunt down a kid for growing a (pot) plant in his backyard, but (I thought) it's not so bad when cops arrest somebody for homicide.
I now believe that this is completely wrong. When the government bans alcohol selling, what happens to the profession of alcohol sellers? Do they become more or less dangerous to society--even from the point of view of their product's effects, i.e. ignoring all the gangland killings?
But that's what happens when government enforces laws against murder: It makes the group of people, "murderers," much more dangerous.
If I told you that the government were going to monopolize the supply of milk, to make sure that everybody got a fair amount and to ensure its quality, wouldn't you poop your pants?
So imagine we're initially in a free society, and then you hear that the government is moving in to town in order to monopolize civil society's possible responses to murderers. Are you going to feel safe to walk the streets now? Are you confident that a serial killer will be stopped as quickly as humanly possible?
Government prisons are awful institutions that on net create more brutal crimes than would occur in their absence.
If you wanted to design a system that created the most awful criminals to date, what would you do? Well, you would want a way to get the most likely candidates for you to train. Maybe you would pick the young people who had been in fights, run from the cops, etc. Violent kids who aren't afraid of authorities, yeah, that's the ticket.
Now that you've got this fresh crop of kids, what you do next is throw them into a confined area with a bunch of career criminals, the worst people your government has ever laid its hands on. And it's fine to let these older guys rape and kill a few of the new recruits; that's great for our ultimate goal, which is to produce a record crop of criminals who are more brutal than any previous crop.
I think you see where I'm going with this...
LEGALIZE MURDER, and all else follows. How could the government continue to prosecute anything else, if people could say, "C'mon, murder is legal, and yet very few people do it. It would wreck your credit score! Who the heck wants that?!"
