What if Government is a disease?

Tough Luck por Bryan Caplan:

"What if a poor person gets sick, doesn't have insurance, and can't get friends, family, or charity to pay for treatment?"

"What if an elderly person gets defrauded out of his entire retirement and the perpetrator vanishes into thin air?"

"What if a child is starving on the street, and no one voluntarily feeds him?"

"What if someone just can't find a job?"

If you're a libertarian, you face what-ifs like this all the time. The point, normally, is to make you say, "Tough luck" and look like a monster. What puzzles me, though, is why libertarians rarely ask analogous questions. Like:

"What if Congress passes an unjust law, the President signs it, and the Supreme Court upholds it?"

"What if the government conscripts you to fight in an unjust war, and you die a horrible death?"

"What if a poor person drinks and gambles away his welfare check?"

"What if the government denies you permission to legally work?"

"What if the President decides your ethnicity is a national security risk and puts you in a concentration camp, and the Supreme Court declares his action constitutional?"

"What if a person lives an extremely unhealthy lifestyle, so by the time they're retired, they're in constant pain no matter how generous their Medicare coverage is?"

"What happens if a President lies to start a war, and voters don't particularly care?"

.. Most people won't tolerate the unpleasant ramifications of libertarianism because they're used to a world where government says, "We'll never let that happen." But what's so great about that assurance, when it's bundled with a long list of other evils that governments blithely tolerate - or actively commit on a grand scale every day?
