let me start by pointing out that i am not using the word "economic" to refer to any and every interaction individuals might have. i reject that perspective completely, and for the purposes of this question (really, for any purpose) i am not interested in it.
i think of really, really free markets (rrfm) as getherings of folks in a particular area, who come together to seek, share, gift and even exchange/trade/barter, in order to meet those needs and desires that could not be met otherwise (eg, diy). this could be a thing, an activity, ideas, anything at all i would think. a key element of exchange in this context is that there is no currency, nothing has any value other than the purely subjective value that the individuals involved in gifting/sharing/exchanging it choose for it to have in that particular moment.
i would not call a rrfm a "gift economy", both for the obvious aversion to "economy" as a concept, and because interactions would likely not always be in that form. the ways in which people interact and meet their needs and desires would be dynamic, spontaneous, and completely up to those involved.
let me point out that in my hypothetical/anarchist world, the daily interactions of life would be in that very same vein, and so an explicit rrfm would be unnecessary. but practically speaking, since people would be in smaller tribes/bands/bolos (my bolo would surely be much smaller than the 300-500 recommended by p.m.), it is likely that some needs and/or desires would not be realizable solely within a single group. and so, rrfms could be a way to bring different groups together to gift/share/exchange. of course that would also be a time to share news, gossip, stories, etc with your neighboring clans.
what do y'all think...?

"neither (rrfms or 'anti-economics') are viable across large, complex modern societies."
i would agree. i also do not think complex, modern societies are very likely to be viable without hierarchical institutions (eg, the state, economics, industrialism, etc). that is why i desire a very different world - of much smaller social groupings - and i try to live my life in that vein in spite of the complex, modern world that exists all around. waiting for the massive changes that are necessary for the world i desire is not something i care to do. i'd rather create my own life in the now, as best i can.
asker: i am not saying it is desirable to replicate anything, rrfms or gatherings of the tribes. i am saying (or asking if, in the context of the original question) those are examples of ways humans can (and have, and do) create ways of interacting that aren't completely subsumed by the capitalist world around them.
i desire for those to be examples not of temporary events, but examples of different ways of relating, particularly around meeting one's needs and desires.
i would much rather find and create different ways of relating in my life, on an ongoing basis, than to not do as such because capitalism still exists. i want capitalism gone as much as anyone, but i also have a life to live; one i will not subvert to some unforeseeable future revolution that eliminates capitalism, the state, etc. i used to think that way, and all it got me was more anger, stress and hatred - and not one iota closer to a world without those institutions of domination. so i realized that i could actually do things in my own life that distance me (and hopefully, at least some of those i care about) from that hellhole. not ideal by any stretch, but a fuckload better than living my life for some future i doubt will ever exist (and i'm fairly certain it won't in my lifetime).
you seem to think that anything short of the end of capitalism is a pointless exercise. i don't. doesn't mean we don't both want the end of capitalism, it just means we will be doing very different things in our here and now.
