What is the advantage in creating an Ethereum smart contract over a regular contract in our legal system (using a lawyer and some pen and paper)?
If code has bugs (and sufficiently complex code will always, always, always have bugs) you simply have to suffer the consequences (sorry for your loss) or the entire community can choose to execute a hard fork and rewrite history (see DAO). If a vanilla legal contract has some typos or even some semantic differences that lead to ridiculous outcomes, lawyers and judges will hash it out. People, not computers, make the final decisions in our legal system, so human errors are mostly tolerated. If I sneak a clause into a contract saying that the other party must pay me their entire salary every year, it would be voided in an instant. Not so if placed in a "smart" contract.
Perhaps you could say that Ethereum is better than our legal system because it's decentralized. But I don't think it's enough to say something is better simply because it's decentralized. Why should I be afraid of a centralized legal system? We elect politicians, who choose judges (who have to be confirmed by legislative bodies whose members we also elect). Sure, it's not perfect, but it's hardly the tyrannical system that would make me turn to the bug-ridden wild west of Ethereum smart contracts.
I think the only reasonable argument in favor of Ethereum contracts is that they are easier to create (less friction, don't need to hire a lawyer, etc), but that's hardly a good thing. Real life contracts are expensive for a reason, not because Rothschild & Co. have some other nefarious plans. You need lawyers to write good contracts and think through their consequences, as well as reasonable, human judges to decide issues when they arise. Ethereum, to me, seems a purely ideological creation, not one rooted in actual needs that people have. Sure, it's decentralized and immutable (unless a contract hurts the wrong people, lol) but did anyone really want that (except for those with ideological reasons, i.e. libertarians)?
Not trying to start a flamewar, I just want to hear a strong opposing viewpoint on this.
