I realize this was meant to be funny, but the libertarian view is very limited government, not no government. Public safety and the common defense are usually accepted as proper functions of a libertarian government, and an asteroid impact probably falls into that category.

So, the libertarian solution is pretty much the same as everyone else: the government rounds up Bruce Willis, a drilling team, and a few nukes, then loads them onto a rocket heading to the asteroid...

There should have been 99.

You appear to have forgotten to convert between dollars and cents.

0.85 cents x 60000 miles = 51000 cents = $510

Which isn't overly high for a set of tires.

Personally, I don't have a problem with it.
