This is why the Stellar blockchain looks promising. On the Stellar blockchain, you put your trust in anchors and issuers (human entities) and each blockchain-subset (roughly the trust-union of specific-token issuers and specific-token anchors you choose) can create a highly distributed / decentralized blockchain from each users perspective, depending on how many anchors and issuers you are willing to trust.

It's a wonderful hybrid of "high-social-trust" networks run by humans (banks, governments) and distributed trust via code / your choice.
