100% decentralisation has more to do with ideology than actual usefulness IMHO.
EXACTLY! I tried to get this point across so many times, to no avail. Everyone on this forum seems to think that decentralization will bring about some magical utopia, and that a government/centralized crypto cannot work because it's not decentralized. I think they need a reality check.
The current centralized financial system has kinda proven already that it doesn't work, this is entirely the reason why Bitcoin was invented in the first place. You may want to cling on to a failing system and a ship that's slowly sinking, but I think we need to improve and do better than that. It's called innovation and progress, not magical utopia.
IMHO centralised finance works just fine, but for example money doesn't move as quickly and cheaply as information (yet) and some processes could be more automated so it might use some of the crypto technologies like distributed ledgers to achieve that. The contribution of crypto to the world should end pretty much right there.
Expecting that a currency like bitcoin will replace fiat is not just optimistic, it's delusional and undesirable.
It would bring only more problems, if anything.
Looks like a bitcoin core developer agrees on "centralised finance is more efficient"

You might agree with it or not, but don't expect it to conquer the world.
