Expensive and slow seems to be the point. An attacker would need to spend an inordinate amount to change just the most recent transactions - this provides high confidence that the chain is immutable and secure. Maybe digital scarcity with trustless, secure transactions is not valuable to you (or the author), but many people do see promise there. Additionally, the "environmental disaster" claims have always seemed shallow to me. Yes, it is a serious issue if everyone is mining with coal powered electricity, but how did it get so cheap? Isn't it on the government to not subsidize coal? The largest mining companies are finding super cheap energy in renewables (1). In the long run, I feel like mining is what can pay for further investment in renewables. For instance, see the article below about Germany paying customers to use electricity (2). Seems like government level mining might be a good investment. 1. https://globalnews.ca/news/3974083/bitcoin-mining-quebec-canada/ https://globalnews.ca/news/3974083/bitcoin-mining-quebec-can... 2. https://www.independent.co.uk/environment/germany-grids-paying-electricity-customers-renewable-energy-power-surplus-wind-solar-generation-a8022576.html https://www.independent.co.uk/environment/germany-grids-payi...
