From my archives, May 2020:

"As mentioned, the biggest issue is the fiat side of the equation. The bright side is that as bitcoin adoption increases, a circular economy should develop reducing the need to interact with fiat at all. Those who wish to accumulate bitcoin will either earn it or accept it in exchange for goods and services leveraging self sovereign software stacks such as BTCPayServer. Most won't buy bitcoin – they will earn it. Most won't sell bitcoin – they will spend it. This reality will take some time to develop and I think we must be able to provide KYC'd users decent privacy - without losing auditable supply - until we bootstrap a circular bitcoin economy."
