Well if the only thing your dad can come up with is people with guns back the euro then perhaps he should reconsider which money he puts his faith into. The people who back bitcoin do so in an egalitarian way, there isn’t a small percentage of the population in charge of how much exists or who can use it and what they can use it on. The entire network of people opting into it do so to avoid the problem of taxation via inflation. Sorry my original comment wasn’t that clear 😅
