这一倾向甚至引起了西班牙的CNT-FAI注意。法国无政府主义者丹尼尔·格林（英语：Daniel Guérin）在《无政府主义：从理论到实践（英语：Anarchism: From Theory to Practice）》一书中提到：“西班牙的无政府工团主义长久以来，一直专注在保护所谓‘亲善团体（英语：Affinity group）’的自治权。这些群体中有著不少自然主义与素食主义的支持者，尤其是在西班牙南部的穷困农工。在人类社会转化为无政府社会的阶段中，这两种生活方式皆被认为适合使用在这段时期内。萨拉戈萨的议会成员，并没有忘记这些‘不适合工业化’群体的命运，也就是自然主义者（Naturists）和天然主义者（Nudists）。这些群体并没有办法达到自给自足的状态，因此议会预期他们在公社同盟（Confederation of communes）的代表将会与其他农业和工业公社达成特别经济协议。在广大、血腥的社会转化前夕，CNT并不认为它们会愚蠢到去满足每个人无穷无尽的抱负[10]。”
贾德·戴蒙在《The Worst Mistake in the History of the Human Race》（人类历史中最糟糕的错误）一文中[15]称狩猎采集是人类史上最成功、最持久的生活型态，相较之下，农业则被他称作“惨剧”（mess），且“仍旧不知道我们是否能够解决它”。依据农业会导致人的预期寿命缩短的相关证据，人类学家马克·南森·寇恩（英语：Mark Nathan Cohen）呼吁，人们必须改变文明代表增进人类福祉的传统观念[16]。
Anarchy is the order of the day among hunter-gatherers. Indeed, critics will ask why a small face-to-face group needs a government anyway. [...] If this is so we can go further and say that since the egalitarian hunting-gathering society is the oldest type of human society and prevailed for the longest period of time – over thousands of decades – then anarchy must be the oldest and one of the most enduring kinds of polity. Ten thousand years ago everyone was an anarchist.

Su obra más representativa es Walden, aparecida en 1854, aunque redactada entre 1845 y 1847, cuando Thoreau decide instalarse en el aislamiento de una cabaña en el bosque, y vivir en íntimo contacto con la naturaleza, en una vida de soledad y sobriedad. De esta experiencia, su filosofía trata de transmitirnos la idea que resulta necesario un retorno respetuoso a la naturaleza, y que la felicidad es sobre todo fruto de la riqueza interior y de la armonía de los individuos con el entorno natural. Muchos han visto en Thoreau a uno de los precursores del ecologismo y del anarquismo primitivista representado en la actualidad por John Zerzan. Para George Woodcock(8), esta actitud puede estar también motivada por una cierta idea de resistencia al progreso y de rechazo al materialismo creciente que caracteriza la sociedad norteamericana de mediados de siglo XIX.
Translated: "His most representative work is Walden, published in 1854, although redacted between 1845 and 1847 when Thoreau decided to move to an isolated cabin in the woods and live in intimate contact with nature in a solitary and sober life. His philosophy, from this experience, attempts to transmit the idea that a return to respecting nature is necessary, and that happiness is, above all, a fruit of inner richness and harmony between individuals and the natural environment. Many have seen Thoreau as a precursor to ecologism and anarcho-primitism, actualized by John Zerzan. For Woodcock (8), this attitude can also be motivated by the idea of resistance to progress and the rejection of the increasing materialism that characterized North American society in the mid-19th century."
