Cryptocurrencies are far more democratic: every time a transaction is submitted the network votes on whether or not it is valid using consensus mechanisms like proof of work or proof of stake.
Fiat currencies are far less democratic: we can only vote for the people that will control them, not for what they will actually do with the currency. In the UK we do not vote for any positions in the Bank of England.
> Monetary and fiscal policies can be used to control the health of the economy. It's part of a wide system that also offers education, medical care, transportation, and many other utilities for actual people. Crypto offers what, exactly?
Monetary and fiscal policies can still operate without control of the currency, see Eurozone members having local policies. All it means is that they can’t arbitrarily print the currency.
> NFTs are worthless garbage nobody can legislate. Digital barcodes. Nation states have robust IP laws to protect and transfer ownership.
You misunderstand NFTs. It is not about intellectual property, it is about property. I can prove I have ownership of any token instantly and trustlessly.
> Crypto wastes energy. It also wastes human brains that could be solving more pertinent problems.
Many cryptocurrencies have negligible energy usage even over the entire network: see Nano. Even in Bitcoin, how is the energy usage a “waste”? It is holding the entire network together.
And with human brains, cryptocurrency research has had very beneficial impact in other fields, see for example Monero’s development of RingCT and Bulletproofs+. And that is ignoring the fact that these brains are reshaping our entire financial infrastructure.
> Quantum computing will render all of the blockchain useless anyway.
Not really. Even if quantum computing was possible now Bitcoin would still be usable. And advancements are being made across all cryptocurrencies to secure them better.
