one of the principles laid out in anarchist writing is that we get to figure shit out as it's coming at us, relative to a set of ideals. and that's really just democracy. saying that we're not willing to write down an authoritative plan is not the same thing as rejecting the principles that have led us to that position. this is the same point as seen elsewhere: it's not the abolition of principles, it's the abolition of enforced rules. the rejection of arbitrary restrictions. it's not a total absence of thought, but a rejection of all authority in controlling that thought. if we don't have a set of ideas, we're not proposing a real system of thought. we're opening up space for ancaps and other people that would oppose our basic values. and, that's inevitably just a hobbesian world of neo-liberalism that pits everybody against each other.
but, all i'm getting at is that you're reinventing the wheel where you don't have to. all of these ideas have been worked out elsewhere. you're not going to get anywhere novel by starting from first principles. taking the time to read through the existing arguments can only broaden your understanding of things, by drawing attention to things you hadn't thought of before and presenting arguments from perspectives you hadn't previously contemplated.
making every generation start from scratch is a surefire way to get absolutely nowhere.
and, if you're going to call yourself an anarchist, you really ought to have defined perspectives, at the least, on what property is, on mutual aid and on distributive justice. otherwise, it doesn't mean anything.
