> 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.
When the votes take money or resources, that's not democratic.
> 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.
It's still representative democracy. You broadly know what politician's platforms are with respect to taxes, priorities, etc. If they do stuff you don't like, you vote them out.
> 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.
So you lose your largest levers so you can make rich cryptowhales happy. Not good.
> 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.
I don't respect your ownership. Neither does anyone else. When your keys leak - and they will -, you don't own it anymore. I'll much sooner use actual laws with records to buy my next house or car.
> Many cryptocurrencies have negligible energy usage even over the entire network: see Nano.
None of the major cryptocurrencies do despite claiming they would for years. I'm not holding my breath.
> Even in Bitcoin, how is the energy usage a “waste”? It is holding the entire network together.
When it's a network that many of us think is pointless, we're simply scratching our heads at this.
> Monero’s development of RingCT and Bulletproofs+.
More crypto junk and not a cure for cancer.
> And that is ignoring the fact that these brains are reshaping our entire financial infrastructure.
It doesn't need changing! We're increasingly building tools to serve the underbanked, and we need the government to continue with AML, KYC, etc. They serve a very valuable purpose of stopping terrorism, preventing bribery, etc.
> Not really. Even if quantum computing was possible now Bitcoin would still be usable.
If Satoshi's keys, or the Winklevoss keys, or Coinbase keys leak, it's game over forever.
> And advancements are being made across all cryptocurrencies to secure them better.
Better hurry. I don't think you realize the clock is ticking. If quantum beats you, it's game over. The network has no value when the trust and ownership can't be proven. Once crypto can attack keys, parties can't prove they own the address. Even if the network is forked or reverted, it's forever broken.
