Anarchism does absolutely nothing to oppose oppressive systems of power but hopes and dreams. Good luck changing people’s minds when communications are restricted in non-liberal societies. Your core tenants are that you reject the power structures required to defend against them. The only difference between you and the original communist revolutions is that you reject the soviets that allowed them to organize a revolution and consolidate power.
This is not the first time I have been sent that source. Your source only proves that it can work in addition to existing power structures or at a smaller scale. If you cannot convince the majority to shift, a couple people are not going to lead a general strike which is commonly held to be a requirement for societal change towards anarchism. You are not arguing the actual ideology of anarchism.
There’s so much that anarchism fails at but ultimately its inability to sustain itself as an ideology means that it will always fail, regardless of if it could work at scale(It cannot) Thus, you are only hurting people with attempts at radical change because the only societies that allow it are liberal ones. What naturally results is opposition in the forms of fascism or a shift to actual communism and oppression. All this while less liberal societies take advantage of free peoples. It is either an unethical ideology or you are proposing it with malicious intent.
