I can't do that unfortunately. Since paying for something in BTC is illegal where I live in. So no merchant accept it either. And me and him doesn't love in the same city.
But I do mentioned to him things like LNmarkets, Bitrefill and nostr zap. To show that bitcoin is the most practical cryptocurrency for payment.
And for things like web3 stuff there is no need for shitcoinery, like we have nostr for decentralized social media, blog, GitHub, and other stuff. It doesn't actually need a Blockchain, not everything have to be using Blockchain
But it's not easy, I think he enjoy the vibe that he got when he interact online with other shitcoiners.
Kinda like How I enjoy the vibe I got on nostr where many maxi Interact with each other
