In my jurisdiction, banks will regularly refund and make whole people who have lost money to scams. They in theory can refuse if they think the owner of the account was careless, but in general they will refund a lot of scams.
One good consequence of this is that scammers now become the banks problem, so they will do more to help educate and prevent scams.
Rather than being able to wash their hands of scams, they will be proactive in making sure transfers are genuine, etc. Of course this can on occasion be a hassle, but in general it's reassuring that the default is not to allow large transfers to "random" people, and even more re-assuring that in general it's the bank who is on the hook for the money.
Of course, in practice it kinda sucks. Zelle requires giving strangers way too much information about you. I won't use it. Much as I dislike PayPal, I use Venmo for this use case.
It is one of its features. The previous method of sending and receiving money involves giving out your bank account number (even if not to strangers, then to PayPal), which means anyone can pull funds from your account using ACH.
