Benefits of centralization: Someone can counteract harmful interactions.
Drawbacks of centralization: Someone can decide legitimate interactions are harmful.
It does suck when the “harmful interaction management system” goes haywire. But I’m not sure it sucks enough that I’d rather simply not have one.
I used to be one of the people firmly on the "someone can decide legitimate interactions are harmful, thus they should not ever exist" side of the argument, and I think this is certainly a good way of putting it.
For a lot of people heavily into crypto, they see the drawbacks of the existing system, but instead of pushing for reform and legal changes, they try technological abolition of the entire mechanism altogether, without then realizing the tradeoffs that brings (e.g. how a lot of people will go "it's instant! Sellers don't have to worry about chargebacks! Nobody can take away your money from you!" yet don't think about how that also means a scammer taking your money is a permanent loss you can never reverse. (or if they do think about it, will argue that risk can be reduced to a point it is less harmful than the alternative, centralized companies)
I don't deny crypto can be useful sometimes, or even be more beneficial when the centralized companies do eventually do something bad and people need an alternative payment mechanism, but I think a lot of people into crypto overestimate how beneficial it truly is compared to the tradeoffs.
About the “nobody can take your money” part.
Etherium Classic exists because somebody hacked an extremely valuable wallet and funneled 13% of all eth into their wallet. The people who control the mining pools, (rich assholes) wanted that transaction reversed, so they hard forked. Classic is the main fork that didn’t reverse that transaction. It’s much less popular, despite being run by people who are demonstrably more principled.
Paraphrased from Dan Olson’s video “line goes up” about crypto’s history and affect on the world. Spoiler: it’s a scam, and a tool for the wealthy to get even richer. Computing power can be bought with dollars.
Technically true, but chains nowadays aren't really vulnerable to that same kind of attack just due to their sheer scale and diversification of controlling stakes compared to what they used to be, so I wouldn't consider it a particularly relevant issue today.
The relevant part isn’t which mistake happened, but that the fact that no mistake can be reversed.
Fixing one mistake is great and all, but it’s still a method of accounting whose ledger — by design — cannot be revised.
