Sharing an app via a redeemed Gift code

Hi all,

So, I've always used Apple Gift Cards to buy apps. Buy a card, redeemed it.

I'd like to gift an app to my wife.

But AppStore demands that I have an another payment method, like my card or Apple Pay.

Why?

AppStore can just debit my gift card, right?
