So I think I can explain why stupid shit like Anarcho-[Insert Unhinged Lefty Ideology Here] can easily be debunked by simply understanding the nature of far-left politics and anarchism. Now there is like hundreds of flavors of Arnacho far-left ideologies to choose from and if I were to try to explain them in detail then I would have to write several big books worth of why these ideologies are bullshit that would bore the average person. Instead I'm going to focus what these Anarcho far-left ideologies have in common.
So in order to understand Anarchy and Far-Left ideals, you have to understand the concepts of Positive Liberty and Negative Liberty.
So Positive Liberty is basically reaping in the benefits of someone's labor. Imagine you are lost in the jungle and you encounter a wild tree bearing edible fruit; it's right there for the taking and no one is going to stop you from eating the fruit and the tree worked hard to produce said fruit, you eat the fruit and you didn't had to do any work so you save your energy and you don't starve to death. That is Positive Liberty. An everyday example of this would be taxes where the government takes away some of the money you earn and is given to various government run programs (like a taxpayer-based healthcare system).
Now that you have an understanding of Positive Liberty, let's talk about Negative Liberty.
Negative Liberty is where you have to put in some work to reap its rewards. Say you want a video game and you go to Gamestop to get that video game but you need to pay for it. Technically you are free to get this game but the only thing standing between you and the video game is the 60 dollars needed to obtain it. So you (like many people) would get a job that pays an hourly wage so one you get your paycheck, you now have the money to buy the video game. This is Negative Liberty, putting in work to reap its rewards.
Now that we got that out of the way, let's talk about anarchy and far-left politics:
Anarchy would be more into the realm of negative liberty. Technically you are also able to do bad and horrible things if you were to be under a state of anarchy (murder, theft, fraud as these would be under Positive Liberty) but you can only pillage other people's belongings and hurt other people for resources for so long so you need to fend for yourself. You find a reliable source of water, you build your own house, you learn to farm, and most importantly you learn that you must be aggressive in defending your resources from an oppressive force because you worked so hard for them.
Now let's look at Far-Left ideals. There's many different flavors of the far-left (regular Communism, Socialism, Marxism, Stalinism, Maoism, Anarcho-Communism, Libertarian-Socialism, Anarcho-Collectivism, etc) but they have one thing in common; they put an emphasis on Positive Liberty. The Far-Left preaches collectivism meaning that the state or some other oppressive force will be like "Give Me That For Free" for the sake of the collective; so if you have resources then the oppressive force will make you share your resources for the collective or else. This contradicts Anarchism because the whole purpose of being in a state of anarchy is to have no one to rule over you.
This is why Anarcho-Communism and other similar ideologies are bullshit because when you think about it you cannot have a totally free society while at the same time have a oppressive force taking on the form of the state or some other form of authority to tell you what to do.
