I agree with der_kil: just do it home with a contained culture Escherichia coli and robots you diy.
Ignoring the state and fake market.
You could become profitable, and still reasonable by accounting how much clients make a year: proof of paystubs or contract salary statement, charge anywhere from 10-∞$, accounting opportunity costs, lawsuits, loss of product, thefts, strain evolution, recombination of cultures, etc..
Bernie Sanders failed to mention standards, taxes, insurance, and all that bureaucratic crap that that USA does to raise the price.
Similar to airplane tickets, international flights cost anywhere from 15$-150$, but insurwnce, taxes, and other shit raise the prices before the opportunity costs games are set.
And yeah, what some companies do during disasters is down right evil, but the market should look the other way.
