Ethics are necessary, but they should not be equated with legality.
A peek at any point in history — ancient or recent — should expose the legality of things as a terrible guide for rightness.
I suggest an ethic akin to the Non-Aggression Principle — don’t hurt people and don’t take their stuff. Otherwise, be as subversive as necessary to undermine corruption.
This spirit is embodied in projects like Dash, Ethereum, and Arcade City.
