My dad used to say the exact same thing, until he lost his job his family, and his life. He used to pretend that he was "functioning", and that his drug use wasn't a problem. This is a classic example of someone who we will read about losing their job and life in 10 years or less.
The only bit I will agree with is that addiction is not caused by the drug itself, and is typically the result of childhood trauma. With that drug use is not a solution for dealing with that trauma, dealing with that trauma directly through therapy and mediation is a much better solution.
Yes, let's return fiat to the gold standard, so that way gold supply shocks negatively impact the entire economy and we get rid of a powerful policy tool. Sounds brilliant.
But do we even need a distributed ledger? Centralized ledgers are easy to maintain in the modern world, and don't require much human energy (or compute energy) to maintain. It is why transaction costs are generally extremely low. Blockchain transactions on the other hand are astronomically expensive and slow. The value of a distributed ledger derives solely from paranoia of a central authority, despite there being little evidence for said paranoia.
