You can say this about anything that uses lots of electricity. Sure, removing it solves the immediate 'problem' but its also not any more practical than having everyone walk everywhere solves the immediate carbon impact of driving. The solution is to invest in more solar, nuclear, and energy storage solutions. Our Earth is already plenty rich in resources to scale up power requirements, and our sun provides near unlimited energy. The energy problem isn't unique to Bitcoin. Using a lot of resources is also the main benefit to the security behind proof-of-work because it makes building a duplicate ledger immensely impractical. The security of the chain actually increases the longer blocks are joined after an input which is pretty cool.
