Sure, assuming every aspect of that contract can be expressed on the
blockchain. Financial transactions with cryptocurrencies can be (I'll
sell you this ERC20 token for this much ETH, if and only if enough
people pledge), but I'm still skeptical that such contracts will be
very useful outside of a few narrowly defined niches.

A smart contract for preordering a new device, for example, has no
idea whether the devices have been shipped, whether they were lost in
transit, etc. The moment you involve humans (which is almost always
necessary), you're back to needing dispute arbitration. A
mathematically inviolable contract does you little good when a key
part of the contract as seen by one of the parties (i.e. actually
receiving the thing) can't be expressed as part of it.
