Yes, but actually no. In the strictest sense that is true in that it isn’t “officially” settled typically for a day or two. However, the reason why businesses are willing to accept credit card transactions is that there’s a soft approval that happens pretty much instantly and weeds out nearly every non-fraud instance of non-payment. Once that soft approval comes back (which remember happens within a second or two) the retailer can be confident that the card is tied to a valid account, that has a large enough balance to cover the transaction, and barring fraud dispute it will go through and they’ll get paid. If something were to go wrong in that process there’s also banks and the CC processor that the business could go after in court to get their money.

In contrast crypto takes several minutes to go through if not significantly longer, and if something goes wrong in that process there’s no legal recourse of any kind. If a business were to allow product to leave their store prior to that minute+ approval process and it fails, they’re screwed, they just have to eat that cost.
