That's an example of sunk cost fallacy, where the miners have spent so much money on otherwise useless ASICs that they obstruct any attempts at progress.

No, the second paragraph was correct. Bitcoin has been a complete failure at accomplishing any of those things you mentioned. They're all just wishful thinking by Satoshi and his fans, that never became reality. In practice it's not decentralized (the network is consolidated into just a few mining pools), it still requires central authorities to validate every transaction (the miners), it doesn't reduce points of failure (see any of the high profile collapses causing lots of people to lose their money) or censorship (historically disadvantaged groups largely aren't using cryptocurrency because it's overloaded with scams). The fixed supply is itself a man-made policy (it's not actually governed by math) and doesn't counteract inflation (see how often the bitcoin market has crashed). The use of renewable energy sources doesn't change that mining is a complete and total waste of energy (see any of the other coins that managed to ditch proof of work). Lightning network is also a complete failure of an experiment that solves nothing and only creates additional scaling problems (see here for a long list of problems, few of which have been addressed: https://github.com/davidshares/Lightning-Network). The number of open Lightning channels is actually shrinking because of how impractical it is to have your own channel (See also: https://bitcoinvisuals.com/lightning).
