The first – many libertarians would argue, the only – duty of government is to protect the nation from other nations and the individual from other individuals. Its instruments are military might and the rule of law.

That duty includes keeping the nation and the individual safe from infectious disease. The law must isolate persons and animals that could make others sick.

It may be hard to identify the infectiously sick. But to the extent that it can the state must do it, and force the infected into quarantine.

The people can insist that the conditions of the quarantine are pleasant, even luxurious (why not, if luxury can be afforded?), but the quarantine must be as absolute as can be.

Right now, Americans need to be protected from the horrific killer disease Ebola. It is known where it comes from; what its symptoms are; what its gestation period is; how it spreads or could be spread. The countries from which it comes should be quarantined.

To take every necessary protective measure would be to prevent panic, not create it.

Fear of Ebola is perfectly rational. It is fearsome. To do whatever is necessary to contain and cure it is also rational.

It is those who say do nothing and don’t even talk about it who are being emotional and unreasonable. Nothing goes away just because it’s taken no notice of.

This horror exists, it has been brought to the United States, now it must be dealt with forcefully, dictatorially, with high-handed authoritarianism – in the interest of freedom.
