>Like for example...?
Venmo/cashapp/paypal are great and basically free for small p2p transfers within the US.
ACH transfers and Wires also work well for larger amounts and have fixed costs, not a fluctuating % of a transaction value like BTC. It's also very easy to send international wires via SWIFT to most countries (including African ones). Most of the countries where it is 'hard' to wire money are under sanctions, a problem that BTC does not solve.
>You have to rely on third party actors and government to facilitate it
Yes, 3rd parties like the FDIC who insure your money for free. You also have to rely on (potentially multiple) 3rd parties if you actually want to spend your BTC on anything. You also have the added complication of price slippage.
If BTC were really better at sending money than fiat-based solutions wouldn't more people use it for that purpose by now?
