I don’t know why it is so hard to get people to understand the difference between libertarianism and anarchy. It’s almost like they don’t want to understand because it’s too useful to hit libertarians over the head with an anarchist hammer.
But for the record:
This is probably the most common definition of a libertarian state that I see in the literature:
- Maintenance of a military, to protect citizens from external aggression and coercion.
- Maintenance of a police force to protect citizens from internal aggression and coercion.
- Maintenance of courts of law to objectively settle disputes among the citizenry.
As far as what is considered coercion, most libertarians would include such things as extortion, overt fraud, ‘protection’ rackets, and most other physical crimes such as burglary, vehicular recklessness, etc. In other words, most crimes that exist today, except for ‘victimless’ crimes such as drug use, prostitution and the like. Anything two adults consent to which does not injure a third would be considered non-criminal.
Of course, there are radicals who think the police and military should be privatized, but their arguments are pretty easy to shoot down. You usually find these types in college dorm bull sessions, where you also find the earnest young Marxists.
Now, outside of that basic formulation, there are other levels of government action that some libertarians will accept. For example, most libertarians I know believe that the state has a role in regulating externalities, on the principle that forcing an uninvolved party to pay part of the costs of a transaction they had nothing to do with is a form of coercion. Hence, you have no right to pollute the air that I breathe or foul my drinking water. And since externalities are by definition a problem the market cannot solve, there is a role here for government regulation.
That said, libertarians are generally hyper-vigilant about the growth of state power, and such regulatory bodies would be kept on a very short string and not be allowed to mission-creep their way into being general ‘safety nazis’ or inventing externalities or exaggerating them in order to increase their power.
Going even further, many libertarians, myself included, believe that a democratic state cannot exist without a civil society, and a civil society can not be maintained without some sort of social safety net. We cannot let people starve in the streets or die for lack of medical care in a wealthy first world nation. Not only is it wrong to do so, but on practical grounds a state so callous would not long survive until there was a popular uprising. Therefore, as a practical matter we need a welfare system and a system of basic universal health care.
But once again, libertarians are hyper-vigilant about encroaching government and are very wary of moral hazards, so most of us believe that if there is to be welfare, it should be difficult to be on it if you’re able bodied, and it should be uncomfortable enough that anyone who is on it should be trying their damnedest to get off of it.
In addition, Libertarians believe that whenever possible private social organization is a much preferable form of welfare than is the state, and that state welfare tends to displace private organization. Therefore, state assistance should be an absolute last resort and not the first place people look to.
Frankly, most libertarians aren’t even that extreme - they’re just libertarian as a direction away from the status quo. Their primary beef with the government is not with basic welfare and such, but with an ever-encroaching regulatory state that seeks to regulate consensual behavior, use the tax code to attempt to shape society, pick winners and losers in the marketplace, control speech, regulate what we put into our bodies, etc. Their primary beef is with agencies like the DEA, the FDA, OSHA, the NLRB, and other intrusions into what they see as the sphere of private contract and free choices.
I should have the right to offer a job on whatever terms I feel reasonable, and you have the right to accept or turn down my offer. So far as no one is hiding pertinent information, no third party has a right to stop us for our ‘own good’ or for the good of ‘society’. There should be no minimum wage laws, no affirmative action, no drug laws except those that are aimed at reckless behavior that threatens others, etc. The tax code should be based on required revenue, and made as flat as possible within the constraints of being able to raise enough revenue to pay for the government we think is reasonable to have. The tax code should not be a tool of redistribution of wealth or social change.
And of course, the state has no right to spy on the citizenry, for any reason absent probable cause in a criminal investigation…
Those are the kinds of issues that animate modern libertarians.
