The core concept is that everyone ought to leave everyone else alone – so long as they are doing the same. It's a reformulation of the Golden Rule, which – ironically – most people say they agree with and teach their kids.

At least, they used to.

Contrast the libertarian concept – the principle of leaving other people alone so long as they do the same – with the chaotic jumble of often-contradictory positions that don't define what a Republican or a Democrat is, because nothing is defined when it is a constantly changing chaotic jumble of often-contradictory positions. One example is the Republican practice of "mending" – but not ending – authoritarian programs such as Obamacare. "Mending" in this context is a working synonym for agreeing with the basic merit of whatever the "program" is but saying we can make it "work" better. Another example is the "de-criminalization" – gaslighting, phone home! – of by definition not-criminal mere use/possession/sale of some "drugs," such as marijuana (and alcohol, too).  It is teeth-achingly incoherent to style a political party as being the "freedom" party when it meters the freedoms people are permitted to have. What you've got is a single party that has a slightly different take on which freedoms it will meter and for what purpose.

In other words, you have the same party.

That is why Voting Harder – whether for Republicans or Democrats – makes no meaningful difference. More people than ever before are beginning to understand this and have decided to stop voting altogether. They have figured out that voting is not just pointless but destructive, as it empowers and legitimizes the illegitimate.

By nature most people still act – in their day-to-day lives – in congruence with the leave-people-alone principle. They don't pester their neighbors; in fact they try their best to be neighborly because they want to be treated neighborly in return. They wave and smile and even offer to help with things sometimes. They don't march up to the neighbor's door, ring the doorbell and hand the neighbor a bill for "services" the neighbor did not ask for or use. Yet these same neighborly people will vote to have someone else do that to their neighbor. This is profoundly morally schizophrenic when you think about it. An action almost everyone understands to be wrong when done by the individual – who would feel ashamed to do it – becomes just a part of the way things are when it is done at a distance, by people sanctioned to do it by this construct called the state.
