Lightning network is non-cryprocurrency ledger that happens to use Bitcoin for eventual settlement. If you are going to use lightning you may as well use a normal debit card.
I'm not sure how "non-cryprocurrency" applies to lightning in anyway. Lightning channels are denominated only in bitcoin. There is no non-cryptocurrency aspect of it. Lightning has many properties that a debit card does not. For example not having to trust a bank to grant you an account, and supporting peer to peer transactions without intermediaries. Debit card transactions are limited from below by fees, fees on lightning are fractions of a penny, thus allowing micropayments that are not feasible with a debit card.
lightning has the perks of being instantaneous, free or nearly free, and not tied to a specific currency.
With visa, it's not instantaneous, charges vendors a 3% tx fee each time a card is used, and requires international clearing houses for foreign payments
