I still don't see why on earth I'd need crypto for "1. Money can be transferred from one person to another without intermediaries such as banks."

Especially as people deal with real fiat currency. Let's say I am at a restaurant. I pay $200. My friend wants to give me $100 for their part of the bill. They'd have to convert $100 to 0.00115987 BTC. Transfer those to me and I convert 0.00115987BTC back to $100. This will incur losses. So I ain't even getting my money's worth.

Or alternatively my friend sends me a wire from their bank account to my bank account and I receive it within seconds. This is country dependent but e.g. here in HK FPS takes 2 seconds and costs nothing. SEPA Fast Payment in Europe is similar as is Australia's NPP or Singapore's FAST etc etc etc. For international my banks all provide free SWIFT transfers. Not instant, takes 1-2 days but hey. Free of charge send and receive for my bank accounts here.

It's a technical solution that can easily be done by banks and banking regulators and doesn't need another 'currency' as intermediary.
