Probably not. You would be right if we were talking about honest, competent central bankers. But most people live in poor countries. Why are those countries poor?
Every country is different, but poor countries are mostly poor because they are governed by kleptocrats, generally including their central bankers, and hyperinflation in particular is a constant menace. When the central bankers aren't directly kleptocratic themselves, they are very often incompetent but loyal, similar to most of Trump's nominees. In this situation, generally speaking, things that put power over individuals' lives back in the hands of those individuals, instead of the kleptocrats' hands, will improve the situation not just of the individuals but of their whole country.
I agree that kleptocracy and incompetence are a important factor, but I'm not sure it's the only one. There's a correlation between corruption indices and low GDP but I'm not sure it's causal. For example the US scores only moderately in corruption index terms, but does quite well in GDP terms. Arguably GDP growth rates are a better measure, in which case there's possibly a inverse correlation.
For example China, India and Malaysia have grown quite substantially are not particularly transparent, but they are alike in their resistance to dollarization. On the other hand Ecuador and El Salvador are examples of countries that have fully embraced dollarization with less than great outcomes. There are examples in the middle as well, but there is not a clear trend that it's necessarily a change for the better of the country and it's citizens.
To me it seems like a continuation of the IMF's dollarization as described by Joseph Stiglitz in 'Globalization and its discontents', in terms of mechanisms and effects on recipient countries. From this perspective it's less like transferring power from kleptocrats to the people, and more like choosing kleptocrats that are offering a better deal.
I don't think corruption indices do a great job of measuring kleptocracy. The PRC's national government, for example, has clearly prioritized enriching the general population through economic development and reducing poverty over lining their own pockets, despite not being transparent or accountable. The indices do provide some information; extremely kleptocratic countries like Venezuela, Eritrea, Yemen, and Nicaragua reliably come out on the bottom of the CPI. But the most damaging effects of kleptocracy are very subtle.
I do agree that dollarization hasn't been resoundingly successful, and that does undermine my thesis somewhat. I agree that cryptocurrencies are like super-dollarization: not only do they remove domestic government control of monetary policy, they remove or weaken domestic government control of and visibility into capital flows, banking services such as savings and lending, and payments. If that would be great, you'd expect dollarization to at least be good. And it isn't clear that it has been. It hasn't been obviously disastrous either—you can make credible arguments that Ecuador or El Salvador would be either better off or worse off without it—but it hasn't been obviously beneficial.
I think "choosing kleptocrats that are offering a better deal" is a good description of dollarization and, for example, Tether, USDC, or CBDCs. But, as a description of Bitcoin and Ethereal, it's comprehensively incorrect; there haven't ever been any credible allegations of corruption in their blockchains, unless you count Ethereal's DAO rollback. They've so far been completely immune to the kind of politically-motivated currency manipulation that is the actual official job of central banks behind fiat currencies like the dollar.
