I should point out that I also think there may be some value in cross border remittance (something like XRPs use case). I do think smart contracts are largely useless though (oracle problem mainly).
I think it's very telling that Ethereum seems to only really have been used for crypto kitties and NFTs (I think we can all agree both are stupid). On the other hand way back when I first encountered the space (2014ish I think) I succesfully (and very easily) ordered high quality class A drugs (with BTC) with really good customer service and without having to deal in person with unsavory peoples (gang adjacent etc...).
EDIT: grammar
