How cool would it be if you could keep something like a sourdough starter (maybe a shelf with a half dozen jars that need tending 1-2 times a week) that would continuously produce the medications people need to live in their own homes.
It would almost certainly be more of a hassle than getting it from a pharmacy, and purification is probably a tricky step, but I think we're just a decade or two from this potentially becoming a reality.
Would be incredibly egalitarian and empowering to individuals.
