I agree about decentralization (most don't care about it), but I wonder if the next two points really make sense. In the first world, most users are indeed doing well with the current financial system, but are most crypto users in the 1st world? The data varies, but the most comprehensive piece I found is this one, where, by a total number of crypto owners, the top-10 countries are India, the USA, Russia, Nigeria, Vietnam, Ukraine, Kenya, South Africa, Colombia, and Venezuela. Clearly, the majority of countries are far from 1st world, and the majority of users (top-10 accounts for around 85% of crypto owners) as well. As for #3, info like that definitely needs to be supported with sources. I couldn't find data on volatility specifically, but I found a recent poll, and people explained there why they invest in cryptos. Top results are easy trading, excitement, potential short-term growth, which are all associated with volatility IMO.
Does this distribution tell you why this is so? Everything is quite simple - this is a list of countries where there is no good financial regulation, where there are "gaps" in the legislative base, where there is corruption, there is no desire to formalize some processes. The USA is probably on this list as one of the most technologically advanced
