This works for the obvious thefts and high profile contracts but what about smaller contracts and more gray areas? Will the miners know about or care enough to actually efficiently resolve disputes fairly? Will there be a fork for the person who lost 500$ because of a bug in his contract? I’m worried that miners policing everything won’t be sustainable and in the end code will be the final arbiter on Etherium and as we all know writing code without bugs is an unrealistic expectation to place on people.
