Amusing how it's gone from "be your own bank" back around to centralization, but this time with a colossal energy footprint behind it. Same shit, bigger pile I guess.
You can always build centralized systems on top of decentralized ones in order to mitigate the scaling costs of decentralization. It's essentially impossible to build a decentralized system on top of a centralized one in order to mitigate the downsides of centralization.
I don't think that's the case. If Paypal wanted, and it was legally allowed, they could anonymize my data to an extent where not even their own team could know who I am. We don't do it because it would be open to fraud and scams, not because it is impossible.
