"or it won't work and break apart at the first supply shortage the community inevitably encounters"
You think like a liberal who does not know what it means to love your fellow human beings or be part of a community.
An anarchist isn't a consumer in an economy, they are more like the members of a vast family of variably strong ties. They are in it together. If there is a lack of goods ppl are supposed to assume the responsibility for increasing availability

Just like a family doesn't fall apart merely because it is poor (indeed, rich families seem to fall apart very easily regardless), a society doesn't fall apart because it lacks goods. It falls apart because ppl don't assume responsibility and take charge.
In an anarchist society, you can hope that somebody else makes a surplus of useful things, but if you want something done, you organize to have it done - production is a grass roots activity.
