PAYPAL HOLDINGS, Inc, is an indispensable, American, global corporation, without whose services, financially transacting online is difficult. The company is worth $16.929 billion.
How is it indispensable and how does it make online transactions less difficult? One can purchase stuff online without using it. And many sites allow the users to provide and store their information in the same exact way PayPal does, without having to pay the fees to PayPal.
The author diverted from Thomas’s argument with that.
Put another way “Bake me a damned cake!!”
If the seller doesn’t have the infrastructure, PayPal provides it. Think things like ebay. Or a one-person craft shop.
