Cheap plastic disposable goods shipped from China on polluting cargo ships are a huge source of environmental damage. This is a direct result of consumerism. Where is the plan to deal with that? Bitcoin energy use is just a stick used to beat it, it is not a genuine concern. Why? Because most people who raise the issue are not green environmentalists, they are just bitcoin detractors. They don't highlight the issues with energy use in other sectors, they don't worry about the emissions from concrete production and building etc. Why? Because complaining about them does not further their goal.
