i think what madlib is alluding to, somewhat poetically, is that there would be no businesses or salaries because there would be no capitalism.
people would build and maintain roads, if they did, because they wanted to, and because a road made more sense than a footpath, in that particular place.
for anarchists who believe that things would basically continue as they are now, only under full democracy, then meetings would decide things like recompense for undesirable labor, and where roads should go, and who would build them.
not a lot of those kinds of anarchists here though.
