"Hey dude, I have 1m sats. Would you accept it for this bike that you are selling?"

"Alright, meet me (some location)"

Few hour pass. Both guys are at the meeting location:

"Here is your new bike"

"What is your node address so I can open a channel with it?"

"Here is the qr code of it"

"Let me open a channel. Wanna go to the café over there until the transaction is confirmed?"

*buyer opens up a channel and pays several $ in fees. he also selects a higher fee so the transaction would go faster.*

"The cannel has opened. What is your lnurl?"

"Here you go"

"Bye"

"Bye"

P. S. Don't get me wrong. Lighting is cool. But it just centralizes the network and most people want things to Just Work™ and wouldn't want to manage channels. Gold isn't perfect either but let's keep physical stuff IRL and digital stuff on the internet.
