I have never trusted PayPal, and especially not when they can reach into my account and take money out without my consent.
I did finally establish a PayPal account, to have available for those rare times when I want to buy something that I can't find anywhere else. Before doing so, I opened a small, senior citizen checking account in a bank different from the bank where I have all my other accounts. I only maintain a minimum balance in the account that's linked to PayPal, and it's isolated from everything else.
That's about the best I can do short of cancelling the account.
