Crypto gives the ability of self custody, I always wonder why people still prefer to use custododial ways to keep their cryptocurrencies in a way they can never have complete control of their coins.
Because majority of people will never want that responsibility, to be their own bank. The more crypto goes into mainstream, the more people will use centralized exchanges and custodial wallets. It sucks, but that's reality and anyone who thinks that people will suddenly open their eyes and ditch all that centralized stuff is extremely naive.
Even if people can withdraw Bitcoin from Paypal they should know that this BTC will now be connected to their identity, in similar way like withdrawing from centralized exchanges with kyc registration.
I don't think that people who are buying Bitcoin via Paypal care much about that, as if the do they certainly wouldn't use PayPal to buy Bitcoin in the first place.
I think nobody really need PayPal, but an alternative payment method might be good.
PayPal used to be quite useful back in the day when you didn't have much options, but situation is completely different now so I guess they have to introduce some changes to stay relevant.
