Why limit this to crypto companies? I personally approve with the specificity of the targeting (I don't see the value added by crypto to society writ large, and there's other power-hungry industries that are more essential who'd likely be crippled by such a tax), but it seems fishy to me to target legislation so specifically, from an engineering standpoint: it won't be flexible w.r.t other situations, and there could be unpredictable outcomes. Plus, if they're getting their power from clean sources, I don't much care about taxing excessive use, but at that point we're just talking about a carbon tax, which is... questionable at best.
