There is a key difference in nature, with some practical consequences.

You don't have money in your bank account, the bank has a debt toward you. When you wire money or pay with a credit card, it triggers a chain of intermediaries to move that debt. It is costly in part because of the counterparty risks. In most countries, an individual however is protected from a bank default up to a certain amount.

Cash is directly minted by the central bank. In a trustless manner, if you exchange goods and services for cash, the settlement is instantaneous. Legally, this cash can be used anywhere in your country.

For everyday use, it might not change habits overnight, but it will have a long term impact on the financial infrastructure.
