I'm not arguing it's more real, I'm arguing you can't cryptographically guarantee how many dollars some entity owns. In this context real life mean off block chain information. Basically the block chain can only verify whats on the blockchain. It can't make any guarantees about off block chain things except that someone with a possession of a certain private key said something at some time.

Sure, a blockchain provides cryptographic consensus about assets on the blockchain, but it can't control things that are not on the blockchain.

Things like legal contracts in a filing cabinet, bank databases, gold bars in a vault, or how many coins I say are in my pocket.

For all those things, the blockchain can act as a database, but you need to trust someone that the entries in the database correspond to these other things that the database is supposedly tracking.

Which is the entire issue the op asked about, can you verify a party has enough dollars to back a stablecoin on the blockchain.
