You are making the same mistake as all the revolutionaries you mention - you completely disregard the problem of efficiently allocating limited resources, and that there are vast differences in capabilities of different people to do it. In other words, merely putting the means of production into hands of workers and asking them to manage these by consensus does not guarantee "society in which nobody has to worry for a place to sleep and food to feed their children". There are some cases which succeeded, yes, but also many that failed.
