Note how ridiculous the counter arguments.

I too have made this argument several times and I have gotten similar nonsense in response.

I recall reading a story about some guy who was visited by police as they thought he was running an indoor pot growing operation, only to find after searching the premises that he was a bitcoin miner. It takes quite a power surge to draw that kind of attention from police. Bitcoin is geeky, and maybe it's idealistic in some good ways, but it's not "green" and it's not practical.

What happens when there's a loss of electricity?

Do we fallback to paper currency then?
