If he'd listen to me I'd just say: "Look Peter, crypto is just an electronic currency alternative that doesn't rely on some gatekeeper who can block your transactions or disown you". "All participants must run compatible software that distributes the computation in a way that no one actor can impose fiat decisions on printing, transfers or property title." "Cryptocurrency is money with functions/features that have never before been offered by any currency. THAT is the value you're not seeing, Peter." "Doesn't mean there aren't possible attacks due to interventions by the State but that applies to Gold as well. Remember Baruch & Co. siezing everyone's gold in the 30s? hmm?" [EDIT: That only applies to legit, well-tested Coins-- not scams like Ripple or the CBDCs]
