The whole point of marketing ivermectin, hydroxychloroquine etc *against* the medical advice is to create a new market for "independent" suppliers - and because it's marketed as "rebel", "banned" etc you can sell cheap substance at prices inflated by a factor of 10x.
In Poland we have a guy (Jerzy Zięba) who made a massive business ($4m per year) by selling very beetroot powder at $4/g while building a "anti-system" image around him, healthcare conspiracies etc.
