Ah, I apologize, but I have to join the unhelpful choir ;) It seems to me that the question of whether or not electricity has mass is a proxy for whether or not information is tangible. This is the same interpretation that "Greg Graviton" at stackexchange has. And it is hard to meaningfully answer by yes or no; information needs material in order to exist, but by itself it is not tangible. Both yes and no are misleading. My advice, which is completely ignorant of how law is practiced, is to find another way to settle the original question of whether or not the coerced obtaining of the virtual sword could be named "stealing". When taking intuitive notions such as "is this a _thing_ or not?" to the fundamental levels, the questions often stop making sense, as it has in this case, because the intuition is dependent on another level of abstraction. At this point it is no longer constructive to attempt obtaining answers to the questions as posed, and maybe this is why you have struggled to find a good answer. That's probably not helpful to you, but it is my best attempt at resolving this question :) (About DC: It is more accurate to say that there is an exchange of mass. The same count of electrons go down the wire as up the other wire. There is no net transfer of mass.
