It depends on what you mean by "use PayPal". To give out my debit card details as infrequently as possible, if a business supports paying with paypal I'll use them as the payment provider. I don't store any money with them though.

You usually don't need a paypal account for that though.

Having said that, it can bite you in different way. Paypal keep an association of last email used in a transaction with a card number.

For example, I had paid for a vps hosting using paypal payment (without a patpal account) with one card, using my email address in the billing details. Later one we bought something for my partner with the same card, but using her email address in the billing details.

Subsequent payments notifications for my vps hosting were sent to her email address.

Disposable/virtual cards are a great alternative to that if you have a good banking system that provides them (e.g.: Revolut in Europe)
