If you can make any sense of this post, congratulations
Its getting popular for the same reason lolcats do, memes. The primary spewers are alex jones for minarchism, and stefan molyneux for anarchism. Stefan equates putting the "golden rule" non aggression principle at the heart of society similar to copernicus putting the sun at the center of the solar system, simplifying a mess of laws, each of which is an opinion with a gun. @gez "Libertarianism is an ideology of tyranny disguised behind a rhetoric of liberty" is an interesting idea.
The main ideology I've heard that might deal with the wealth gap problem is the zeitgeist movement. And they have some points, like a city block has multiple cars for every house which is economically inefficient.. maybe a handful of cars for each house to borrow whenever instead, and planned obsolescence like lightbulbs lasing 5 months instead of 100 years deliberately so you have to buy more. They basically want science to run everything. Alex Jones fears its tyranny in disguise, like who programs the big computer that runs everything, and what if you don't want to opt into that system. In a free society/free market a group of people COULD opt into such a system voluntarily if they all agreed to do it. People could voluntarily opt to have a government even. In our current system people can't opt OUT of government.
Some say government is a "power monopoly".. but I wonder if the world is a power free market and each country is a competing "power business".. These power businesses are for sale of course.. to corporations. But tax payers HAVE to fund government/war. You HAVE to vote for government and government school. You can't not vote for government, with your dollar nor your actual vote.
One political tactic is for statist/authoritarians to camouflage themselves as libertarians or environmentalists etc; deception, just like an angler fish pretending its lure is food. Like al gore and "carbon taxes" taxing us for gas that plants breathe "for the earth". Conspiracy theory? I'm sure they absolutely regulated cars because they know almost everybody NEEDS one.. smog checks, registration fees, licenses, required insurance.. all a tax disguised as safety, since everyone needs a car just like everyone needs to use carbon dioxide (maybe I'll walk down the street someday and someone will just hit me in the head with a golf club.. do I HAVE to buy golf club insurance?)
One thing that might hold anarchy in balance is reputation, but anonymity throws a wrench in that. You could consider an anonymous person as having 0 reputation history though. Like if you don't have to work till may for free to pay tax, and drugs aren't illegal to make a black market to drive prices up and take down competitors with law, and the free market wasn't regulated with all these crap licenses and such, people would have more incentive to simply participate normally and cooperate to build reputation for future business rather than risk all that future business by cheating/stealing/etc once. In a free market, everything would be under absolute scrutiny with free press. There'd be no "power monopoly" (you can fund or not fund any one) so if one appears to be hitler like, stop funding it. In reality I suppose the wealthy would be their biggest customers.. But there's this idea called "dispute resolution organizations" which is basically alternative free market legal systems. If someone steals or whatever they can pay their debt economically by working IF THEY WANT, otherwise they'll get bad reputation similar to "credit ratings" which will cause many businesses to ostracize them, which isn't a violation of the non aggression principle.
So, uh, yeah or something.
