If we didn't pay taxes we wouldn't have schools, roads, or the internet, and maybe even your mortgage (along with countless other things). So imagine where you life would be without it.
That strategy only works because other people are paying taxes and mortgages.
I'm actually a big fan of a Stateless, decentralized society. But you can't reach that place just by Galting your way there. You need at least a modern city to go with you.
You know, it's easy to dunk on these folks. Especially since the American Libertarian party has allowed itself to be infested with a lot of silly and even racist people. But globally this crisis does show that the "decentralize and democratize" sides of the political compass have a point.
In the US, central authority substantially impeded pandemic response. Both out of apathy (substantially defunding and deprioritizing support in 2018) and selfishly, with key CDC officials acting on behalf of the executive to suppress key information and decline assistant from other countries (and the WHO) who have better testing infrastructure.
We only discovered the Seattle COVID-19 outbreak because a (heroic, imo) doctor decided to destroy red tape that was blocking her from doing important work [0]. The US has been refusing to evaluate South Korea's current treatment method [1] which is clearly saving lives.
More in my camp, the notion of enforcing borders is hurting us more than protecting us in a lot of cases. E.g., border control chokepoints in airports are creating infection hotzones that are going to do much more harm than good. Great job loading everyone with a nascent infection and then sending them out into society with no possibility of tracing where they got it, customs! Way to do exactly the opposite of whatyou wanted to do! [2]
Even more ridiculous is how currently US IP law, a longtime foil, is being used to hold up giving Chinese citizens access to potentially very effective antiviral drugs because Gliead is afraid China will undercut them. [3] Sure the world is on the brink of a global economic collapse and in the worst case a few percentage points of the global population could die and the majority of people living could see their lifespans shortened due to complicatons, but yeah let's worry about that quarterly stock price and IP law.
Libertarianism in America is rife with contradictions and racist buffoons, but right now I think there is a lot of positive things to be said about decentrialized and anti-authoritarian societies. It's certainly hard to imagine them doing worse than our current government.
