No, the profit motive is not the only reason why someone would consider blocking someone’s light to not be in the same category as burning someone’s house down. Because it isnt qualatatively anywhere close to being in the same category. It’s a matter of common sense and people’s normative notions - blocking someone’s light is not a rights violation.
Bullshit. Such views do not inherently follow from evolutionary thought. Herbert Spencer would be rolling in his grave.
The “modal” category (which is a term that the white-nationalist-parading-as-a-libertarian “confederalsocialist” on youtube likes to use) is a strawman of the position of most anarchists (noone has ever claimed that absolute unanimity is required in order for society to be free). Even “thin” libertarians believe that, by the very least, the NAP is a necessary condition for anarchism, which is why it’s called “libertarian anarchism” - and the amoralists aren’t even “thin” libertarians. They’re no kind of libertarian at all.
The claim to “pragmatism” is bunk - the theory of how anarchy will work coming from the amoralists is, in fact, not pragmatic. It is so open-ended that it no longer can even coherantly claim to be anti-statist, since it has relativized the normative basis from which we could possibly even define statism. In practise, it reduces to the exact same thing as statism, only with an emphasis on a larger plurality of states that control smaller geographical areas. That’s the “pragmatic” reality of such conceptions of “anarchism” for you. “Pluralism” between territorial states is not anarchism.
Even when the intent is not legitimization, the function is legitimization. It functions to legitimize any sort of state or authoritarian social order on the grounds that it co-exists with a plurality of other states or authoritarian social orders.
