That'd require them to hold your Bitcoin for you, so they could just move some from one person to another. Isn't that counter to the Bitcoin philosophy?
Ideally everything would be self hosted p2p btcpayserver like technology. But mass adoption requires some compromises. Not everyone wants to self host and self custody, and if you’re willing to compromise a little on that you can have massive UX gains, especially if you’re looking to swap to fiat on either end anyways. As long as you retain the ability to self custody your currency should you desire, it’s not even that big of a compromise IMO.
I believe that’s what they do currently. I made the mistake of buying some LTC recently on PayPal. Turns out you can’t actually send it to any other LTC address ... your options are only “buy” and “sell”.
