I consider myself a libertarian socialist.
I grew up on the writings of Ayn Rand, and to this day I believe she made an excellent argument on behalf of capitalism and individual liberty. I have also been a registered member of the Libertarian party, voting for several of their candidates, and score far closer to the libertarian than authoritarian end of the political compass.
The turning point for me was the realization that corporatism mandated the same sacrifice of the individual to the collective which Rand demonized communism for- When being made to surrender your personal liberties, it is irrelevant whether it is to the state, the church, or to the company. A worker in a mining town is no more free under the thumb of the corporation than a dissident is under a totalitarian regime- In fact, I believe the argument can be made that he is less so, simply because of the illusion that he has chosen to be there.
I also happen to view government not as a means to subjugate the population, but rather as simply the way a society pools resources for the common good (Colin Woodward makes an excellent point in American Nations about how these two viewpoints are closely associated with Appalachian and Yankee values, respectively). Admittedly, mine is an ideal, rather than evidentiary view.
So, at the end of the day, I define my “libertarianism” as a commitment to maximum personal liberty. I further define liberty as being at the end of a spectrum where one has the largest number of meaningful options available to them.
“your money or your life”, “vote for el Presidente or we have your family killed”, “love god or burn in hell” are all choices, but they are not meaningful ones. The individual has no control over his/her participation in them, or any ability to change the surrounding circumstances. Most importantly, this can manifest in more subtle ways: Tell me I can only eat in an Indian restaurant, and I will have almost more options than I can choose from; But if I have Chinese, Thai, sushi, and Italian all available, my only option is a salad- Because my allergies to soy and peanuts, my carb-free diabetic diet, and my dislike of seafood eliminate everything else on the menus. While I technically have many more choices in the second case, they aren’t meaningful ones- Because I’m not actually free to choose them.
So, while the free market is the ideal solution to most things, we have to recognize that “free” can’t exist without the absence of coercion- and what most libertarians do not understand is that that said coercion is not always as obvious as a gun to the head- A drowning man is not free to negotiate the price of a life preserver, and it makes no difference that the man providing it is not the same one who pushed him into the water.
Hence, where the “socialism” part comes in. A society which has things like roads and telecommunications and running water freely available to me affords far more meaningful options than does a society without. The less outside coercion I feel to enter into say, an employment contract or a lease, the more freedom I have to accept, decline, or negotiate that offer- So the more things like UBI and healthcare there are, the more freedom I have.
Therefore, it is worth it to me to pay the price of admission (taxes) to participate in that society, rather than say, moving to the middle of the African desert where I can be free from government interference, but also from things like, you know, everything else.
And from a free market libertarian viewpoint, that makes sense to me: I pay a fair price to live in a place which provides value.
