It depends on *how* libertarian.

Radical libertarians think that the government should not collect any taxes, and should spend money only on law enforcement and military.

Which means: no Social Security. No highway funding. No public eduction.

And that is inevitably going to lead to pockets of impoverished people, where grandpa is begging on the street, Dad is dead, and little Timmy is just wandering around waiting for grandpa to die.

Libertarians are against law enforcement and military spending just as much as they are against other kinds of spending.
