>>7634403scarcity always exists. there's scarcity of bread, cars, etc. because they're not unlimited. someone has to make them and be compensated for labor. you know what isn't scarce? air.
this commune approach fails because there's bound to be a conflict of interest even in smallest group because resources are not air. the most efficient way to distribute them has been based on free market principle.
the question is not "why are you so selfish"; the question is "why the fuck you think you're entitled to it when you don't you give back enough in return".
people in commune approach are asked to sacrifice themselves for others, which is basically parasitism of others on individual. this kind of altruism can exist though. but it requires complete and total trust and definite necessity. it is something that is seen as the ultimate way to build society in Christian dogma. but the truth is, it's only truly achieved between a parent and a baby, or with a wife, because if evolutionary advantage to continue family.
you can treat close friends like this, but it's not like you're gonna gift them a lot of money or something. this is just not normal; what are they, your baby? and even then, it's mutualism. one doesn't just give for free, they get something in return, like future favors, or at least they get company. if they don't get something, they naturally feel betrayed and quit. this relationship rests on a code of conduct. on assumption that people will get equal benefits, and manage losses. it's not just giving selflessly.
the bigger the group, the less certain promise of return becomes, if only because of size and management hardships. it needs accountability system. it exists. it's called money. don't have money but promise something later? there's credit and debt.
finally, what if the group demands something to remain strong? then why don't they pay for it. if they don't want to pay money for it, then perhaps they don't value the group much to begin with.
