Re: Crazy power consumption
OK, well, I can find figures for 2019. Netflix streamed about 60 billion hours of content that year.
Their own energy usage was 451 GWh. To that let's add the energy usage of devices showing that content: if we assume the average viewing device is a laptop, it will be using about 60W, so 60 billion hours translates to about 3,600 GWh, for a total of a bit over 4 TWh.
Bitcoin's energy usage that year was - well, frankly I can't see quite how to read this graph, but the range of estimates seems to be about 50-75 TWh.
Bitcoin wins by more than an order of magnitude.
Also I can't see how you argue that "the world would be better off without Netflix", while also being prepared to defend Bitcoin on the grounds that people who use it clearly do find value in it. Those two positions seem quite unreconcilable to me.
