But that is the same principle even in anarcho-communism, syndicalism and what else have you. There must be a general consensus with the people to abide by the social compromise, that living together means sustaining each other for the better good; which means that you do not coerce someone else to do something.
I missed this post earlier, and I need to respond.
There are a few things in society which require consensus, but not many. We are better off when we don't need to rely on this process. Individual people have different preferences and goals. There will always be people who do not agree with each other about what to do with scarce resources, for example. There is no 'hive mind' among humans that locks-in to the global optimum solution to such problems. It is thus
this idea of requiring consensus for decision-making - and not the real and observable dynamics of the marketplace - which truly deserves the term "magical thinking."
Lacking such a 'hive mind', any so-called "consensus" decision that must apply to all members of the group will
necessarily leave some portion of the group dissatisfied. If instead we are free to choose what to do with whatever scarce resource that is our legitimate property (those things which we have acquired through homesteading, productive work and mutually-beneficial trade),
and we do not thereby violate the property rights of others (via pollution harms for example)
then we do not come into conflict with each other.
Instead of collectively deciding what to make out of a pile of iron ore, we can individually choose which uses of it meet our subjective, individual highest goals (ends) - a transaxle for our car, a fancy sword, or a new steel cooking pot. Instead of all agreeing that we must all eat hamburgers for lunch on the first of the month, we each choose that meal which we individually deem most preferable. Instead of 51% happy hamburger eaters and 49% who would have preferred something else, we each get what we want most. Instead of requiring children to be incarcerated in the State school system for twelve years, they and their families can choose the most suitable type and amount of education, and they can enter an apprenticeship or professional training whenever they are ready.
Wherever individual choice is allowed rather than a one-size-fits-all collective decision, we avoid creating discontented people and we avoid wasting our time and energy on unproductive fighting over decisions which must apply to all. (Think of multiple Pyra colors available instead of just one.)
And for those things which
do require a degree of consensus - our idea of law, right and wrong, and socially inacceptable behavior - what do we need? Well, we need
consensus - shared traditions, ideals and values
- and that is only the result of a homogeneous culture! Any deliberate or inadvertent importation of significant numbers of people from a different culture makes genuine consensus building more difficult, or even impossible.
