Earlier quoted context omitted.
We thought this and killed our PayPal integration (went Stripe only) and lost double digits in sales (and received constant emails asking for PayPal). Unfortunately people want PayPal for whatever reason. Everything about PayPal from the merchant side sucks (bad API, bad recurring billing features, slow, no refund of fees for refunds from May, 6 months for someone to do a chargeback!, etc etc)
Paypal is just another "you pay for convenience" service. Not having to type in your card details for every site means you can impulse buy any time you want. Another draw of Paypal I remember 5-10 years ago was being able to use money obtained on consumer-to-consumer markets. If you were to use any other p2p service (be it venmo, cashapp, etc) you would be required to have a bank and your money almost certainly will…
And your shipping address. That's the killer app for me.
One email/password combo is all it takes to get whatever random thing I'm looking at into my office. It's a real convenience.
