Well maybe we should ban gold mining instead of bitcoin mining. It uses more energy and anyone who can understand the source code understands that Bitcoin does gold’s job, only 10x better.
1. Gold is used for other things than just investment, including jewellery and industrial uses (principally electronics). Can you plate a connector with Bitcoin?
2. I'm willing to bet that the economic multiplier for money spent on a gold mine is far higher than a crypto farm. Even looking at job creation alone, gold wins.
3. The literature [1] disagrees with your assertion that gold mining uses more energy than bitcoin generation.
