That's not the point at all. Currently I'm using paypal to send money to friends when we split dinner or share other costs. I'd like to use a similar European service instead and not go through a ceremony to open my banking app, initiate transfer, write the recipient's IBAN, confirm and wait a day for the transfer to take place.

Wero and Bizum mostly just associate phone numbers to IBANs and perform instant SEPA transfers underneath. The benefit is that you only need the other's phone number to send them money, usually already in your contact list, instead of them sharing you a twenty-something digit number.

Ah yes, Pierre will surely have no issues paying for his baguette et croissant by filling in the boulangerie's IBAN on his mobile phone and waiting 15 minutes for them to check receipt.
