Libertarianism requires its members to engage in due diligence in order to execute their libertarian ideals properly and make the choices that are correct for them.
This, unfortunately, excludes the lower-60% of all Americans, who are so ground down, economically terrorized, and mentally overwhelmed with their daily struggles to survive that they have little to no opportunity to approach any major choice with anything even vaguely in the realm of due diligence. They just don’t have the headspace to do so, and are forced to spend all their available mental efforts on just putting one financial foot in front of the other.
This is why having social support frameworks enforced/provided/funded by the government is so important for so many working-class people - it allows them to put those issues on autopilot, significantly reducing their own cognitive load and allowing them to better process the most important issues in their lives.
Ergo, libertarianism is a wealthy person’s toy. It is something that they can champion, because only they have the economic options and financial freedom to fully and properly engage with it.
Until everyone has vanishingly few catastrophic-level issues on the horizon (like one missed paycheque leading to homelessness, or a sudden illness leading to medical bankruptcy), any attempt to implement libertarianism will only bring mass amounts of misery and destroyed lives to anyone beneath the Parasite Class.
And when you have those kinds of widespread government-provided supports that lift all boats - and not just the megayachts - why bother with libertarianism? We should continue to use what got everyone into that safe state in the first place -- socialism.
Remember, the Parasite Class already uses socialism for themselves. It’s called grants and bailouts and subsidies, and allows the Parasite Class to privatize the profits and socialize the losses.
It’s just at a scale that makes it impossible for working-class people to leverage.
