OK, so accepting this, is my concern that legalisation/decriminalisation would risk a social cost of people being able to get off their face all day every day for the price of a lettuce (a) a legitimate concern or (b) "No actually Steve, the production costs and logistics are such that it's not really feasible, by the time you've finished it's quite an undertaking and cost to produce enough to make it worthwhile"?
Because without wanting to go down a rabbit hole of accountancy of costs, that's one of the possible concerns. I know, as has been pointed out elsewhere, that I could homebrew alcohol, and I have, but the quantities you need are fairly substantial. There's a lot of dicking about with buckets and bottles, and if you use say apple juice as a base it's not free.
