I am against recreational mind-altering drugs and all forms of pornography, but I really like the dark market model of business transactions.
I'd be happy, for instance, to buy an "America First" hat or t-shirt, but I'd prefer to pay with #Monero and use a PGP key to communicate my mailing address over the Tor network.
XMRbazaar is a good example of this kind of transaction (it's how I bought my GrapheneOS phone), but it should be more widespread.
