There are two kinds of privatizations: 1: The real kind, where the government simply stops doing an activity (or does it too ineffectively) and a market appears out of opportunity - like SpaceX. Libertarians like this because it makes the government smaller. 2: The fake kind, where a government decides that something it does should now be done by a private entity under contract. Blackwater is one example, most privatized railways are another. These seem to port the annoying bits from government (the private operator is accountable to the government, not the "customer", and there is still no competition) and while the typically predictable cost is good for budgeting, the real benefit is too often in keeping politicians' fingers out of day-to-day operations. Most libertarians would prefer you'd just get the governments hands out of the operation altogether.
