Why is PayPal not an option to receive payments?

Squarespace advertises as being integrated with PayPal, but after signing on with them, investing time and $ to create the site, it says that I am not able to use PayPal to receive payments. And there is no way to know this ahead of time, since it does not allow the site creator to set up any form of payment until an actual sale is made (WHY) - once that happens, then it says PayPal is not an option. 

Clearly the ability is there to interface with PayPal as it is an option for customer to use in order to pay. 

So why isn't it an option for the site owners to use it for receiving the payment? They just want all of my information? Bank account and everything? What's next?

Let's recap: Ecommerce customer visiting my Squarespace site can pay for goods using PayPal. Squarespace will not allow me to receive the payment using PayPal. 

I found that in a different section of the menu, not where it says Action needed to receive payouts 

with the call to action link, no not there of course, but further down below in a separate section (below where it says 'Manage Settings')  it appears that PayPal is an option to receive payments - so I went through the process to connect it -

However, the option says " 

Then the process to connect prompts me to login to Paypal and asks to verify all of my personal details - so, one would think, that I would be able to receive the payment directly from PayPal, right?  Otherwise, why does it need me to log in, why would it need all my personal details? 

But it also still says " Action needed to receive payouts" 

 with an alert at the top saying Connect a checking account to receive payouts 

So, can anyone answer, can we get paid through Paypal? Or have I been subjected to more information-stealing? fingers crossed hoping for the best. very annoyed right now. hoping my identity isn't stolen.
