Having a single European-wide integrated pull-based payment method is great for cross-border commerce. When I went studying abroad, I just gave the rental agency my IBAN, and they pulled the rent from my account the same way my local landlord did. I can sign up for services from any company in the EU and have recurring payments just like I would for local companies. That's not as easy if there's 27 national methods.
Furthermore, I don't think SDD is a big fraud risk. To be able to make direct debits, you need a contract with a bank, and, at least in my experience, they're quite thorough about that: you need to have a legal entity, banking history and show government identification; and even then the amount you can direct debit is limited to just a little more than your usual turnover. If a fraudulent debit happens anyway, you can one-click, no-questions-asked reverse them for up to eight weeks. After that, you can report it as an unauthorized transaction for up to 13 months and the bank will reverse it unless the creditor can show a signed mandate.
I don't think I've ever heard of anyone having had a direct debit from an unknown party. At least over here in the Netherlands, all banks also support requiring pre-authorization for direct debits nowadays, eliminating the risk completely.
