Yes... although that would only be the most 'mundane' aspect.  It's a smart contract platform, with all that entails.  So it's very possible to use it for crypto-to-crypto, but equally possible for fiat-to-crypto, or for that matter fiat-to-gold (with BC only playing the part of escrow 'insurance' funding).  Eventually it's possible to even use smart contracts for things that aren't necessarily even physical tangibles... like employment, franchise licensing, annuities, etc.

Basically if you can program the business logic behind any form of agreement between multiple parties - you can create a smart contract and back the transaction with cryptos.  Not sure how widely adopted such things will be for several years (look at how long it took before scanned images of documents were considered legally valid)... but eventually, I can't see why everything that we currently use paper, property, lawyers, etc. for won't be done in a purely electronic fashion.
