Visa is NOT instant. VISA transactions take up to 48 hours to clear. And in some cases the credit card processor can and will hold funds for even longer than that.
Some do, but some like Square will pay you out next business day free of charge or instantly for a small surcharge. To your point they’re floating that during settlement. It’s instant in the sense that the transaction is approved instantly and the settlement is a formality.
Settlement is not a formality. Money still has to change hands behind the scenes in various bank accounts. The only thing that's instant is the check for available funds. The actual transfer of money still occurs via ACH.
Within the US, ACH is being superseded by RTP realtime payments. SEPA is realtime in Europe. It's a formality from the perspective of the customer because the payment 'happens' immediately, and the merchant gets paid out within 24 hours, sooner if they really need it. Is this really a problem?
But still, definitely a promising improvement over ACH.
It is a practical problem that the merchant has to wait 24-48 hrs for funds. It's a cash flow problem. It slows down the speed at which that cash can be used to purchase other goods or services. For example, a made-to-order business has to wait for funds to clear from a customer (or front the capital) before they can turn around and order goods to produce the product a customer is purchasing. Which slows down delivery. And that effect is amplified across the whole supply chain.

No. That's what lending is for. Square will allow you to cash out instantly for a 1% fee, they offer merchants a debit card they can use to access the funds in real-time as they're received for no additional fee, or you borrow some amount of float at today's incredibly low interest rates.
As a business in need of liquidity you can even sell your accounts receivable for less than 1% to invoice factoring companies. There's so many options out there.
Or the merchant can open a credit card and get fee-free interest-free loans for a whole month.
This is not an issue today, or rather, you’re making mountains out of molehills. There are ways of addressing this without crypto or throwing out the existing financial system. But more importantly what how many merchants wait for funds to clear before they go out and buy the supplies to do a job?
