Anecdotally I’ve personally seen a lot of “Bitcoin accepted here” signs while traveling around America. It’s not ubiquitous, but it is there. Hell, I bought a plane ticket with Bitcoin way back in 2014 for a family member to come see me.

I’m not sure if you’ve ever heard of the “lightning network” but it uses some really clever cryptography which allows people to send/recv Bitcoin almost instantly, with finalized settlement done on-chain as a normal transaction when the payment channel closes https://en.m.wikipedia.org/wiki/Lightning_Network

The other thing about payment finality is that thanks to blockchains with smart contracts (so not really on Bitcoin) things like escrow become pretty simple to conduct. You can write programs to enforce exactly how an exchange should work (“only release payment after proof has been posted to the chain”), and both parties can have confidence that no one is getting taken advantage of because they’ve agreed to immutable rules beforehand - to me that’s a super powerful primitive to build neat stuff with.
