Not a lawyer, but a contract requires that all parties must gain some consideration for their entry into the contract. That the blockchain enforces the proposer's "smart contract" without giving material return to the token-holders means that the proposer's claim is unenforceable in a real-life court. No consideration, no (real-world) contract, no breach if some consensus fork emerges.

same ianal disclaimer, but here's the thing, this was built for allowing anonymous contract participation, if you can't participate in a contract without agreement from all parties that'd put the whole smart contract to an end. everyone would be able to seek damages from etherium from transactions they didn't like
