- Crypto is an environmental disaster. The blockchain eats up energy that could be used to do more productive things. To be fair, eliminating proof of work could mitigate the problem, but it's not going to happen for old crypto currencies like Bitcoin.

- Crypto is used for laundering billions of dollars by organized crime.

- > It's also a good way to subvert government control of the economy.

I fundamentally disagree on this one. An economy without any government control is not desirable. It also may not even be *possible*, since for the economy to work there must be an assurance that each participant in the market can keep their property (and not have others take it away unlawfully), and who but the government will ensure that? I see many people talking about the greatness of a decentralized currency, because it allegedly will give power to the people, but in reality I just see people selling, buying, basically another stock market, only with less government regulation.
