These posts neglect the fact that if you're using Coinbase/VISA, your identity is already registered with these entities. If you try to fleece them you get got.
If I walked into a cafe where nobody knows me, got a coffee, and sent some BTC using a personal wallet - don't you think the owner would want to wait for confirmation before letting me leave? Wouldn't I have to wait at the door for 10 minutes awkwardly holding my coffee?
That's the point I'm trying to make.
wire transfers take 3-5 days in most countries. yet visa/mastercard which is a layer above FIAT aid in this process by ensring the transaction occurs and allows pople to leave starbucks as soon as they have made the transaction request.
what will happen is that starbucks will have a membership card that is a starbucks controlld walet. people deposit funds in at the start of th week/month. and then when walking into the shop they simply give the permission to allow starbucks to take out X amount of pre confirmed btc to cover the cost of the coffee.
there will be many services for microtransactions that have wallets for pocket money amounts to be preconfirmed to. and then merchants can simply take funds out in batches whenever they please
