Ayn Rand was - so far - the greatest philosopher of freedom in human history. She was the advocate of "minimum state" but not anarcho-capitalism. She thought that it can't exists without violence, but we now know (thanks to Rothbard, Misses and so on) that it's possible. "The Fountainhead" by Rand is a really good place to start seeking values, ethic, philosophy.
Ayn Rand is not Aristotle, but I upvoted you per your passionate appreciation of Rand.
The best I can recommend of Rand is "The Virtue Of Selfishness", however minarchism has proven to be a bus to nowhere and we all know what Greenspan devolved to. Anarcho-capitalism or else; freedom wins by default.

There will be about anarcho-capitalism too. I also consider it as the better solution than "night-watchman state"/minarchism.
Enjoy your freedom, you deserve it.
