I don't know if I'd take these ideas seriously, especially from PayPal.
Assuming it's still owned by eBay, its probably just trying to get some demand on ebay stocks (since they just seem to fall relative to their profits).
Also, I don't know if anyone uses PayPal for any other reason than it being useful for not putting in card details when paying for stuff, if you instead have to bother to sign a transaction or do something fancier then why would anyone bother?
All this being said, a centralised organisation controlling a cryptocurrency might make it more forgiving from scams and accidental mistakes (eg sending to addresses spelt wrong).
They (eBay) no longer owns PayPal and they have actually become somewhat “enemies” since splitting up but the premise here is the same, PayPal is one of that worlds most corrupt organizations and should not be trusted by anyone. It amazes me that people actually buy and store bitcoin and crypto through them. Steer far clear from these scumbags everyone !
I see that you are extremely negative towards PayPal. I think these three people will agree with your position:

This article describes the story of a recent lawsuit by PayPal users whose accounts were frozen with the confiscation of almost $ 241,000 of funds by the site. At the same time, there is a very important nuance. Initially, PayPal did not tell these users exactly which clause of the agreement they violated. This means that the platform allows itself to be blocked without explanation.
My suggestion is to shut down the emotions and use platforms like Paypal if it's profitable. But you need to do this carefully and at your own risk, since any centralized organization, Paypal, can unilaterally break off all relations with you and block your funds.
We should not forget about such unpleasant cases and need to be prepared for them.
