You surely don’t think that actual dollars settle every time you pay with a credit card, Venmo, or PayPal? You realize that settlement takes weeks?
Micro-paying with Bitcoin on a centralized platform like PayPal is essentially the same as dollars. Final settlement in BTC can come later when someone wants to withdraw their balance.
Credit card settlements happen next business day, not after weeks. Venmo and PayPal transactions settle instantly. You can spend the money immediately. PayPal also supports instant bank transfers, so you can transfer it out and withdraw it from an ATM as cash a minute later if you'd like.
They are referring to cash settlement, not spending ability, I believe ("You realize that settlement takes weeks?"). The difference is nearly unnoticeable to the end user, whether or not the actual cash is moved, because they can still spend it.
