No. In the European countries which no longer have cheques (or where they are very rare), the electronic banking systems have strong regulations which should prevent major problems from PayPal having access to a bank account.
If PayPal take money from my account and I don't like it, it's a few clicks in online banking, or a phone call to the bank, to reverse the transaction and block any future transactions.
It is the same system as used for an electricity bill, where a variable amount is collected each time.
