I hope this is not spoiler (I don't know if you're planning to read Harsh Mistress some day) but you're not taking into account that the districts are too small to be self-sufficient. Within that limited territory there's not enough water and not enough space to cultivate food or raise livestock in enough quantities to supply their inhabitants every day for extended periods of time.

Remember that when Sasha stole that piece of meat right before the second appearance of the Colossus Titan, Eren said that meat was a very rare and valuable food because the lost of Wall Maria had heavily reduced the spaces for livestock; and we are talking about the combined territories of Wall Rose and Wall Sheena with all their districts. How much cattle and how much food do you think could be produced in a single isolated district? Sooner rather than later people would have to abandon it and went to Wall Rose or await their deaths in there.
