Wrong. Running a node is about self defense. In many ways it's the online equivalent to owning a gun. No 3rd party can fudge your UXTOs or selectively show you what they want you to see when your own node is directly interfacing with the blockchain.
Sure, most wallet providers don't want to screw you over, but this is a lazy argument that sounds too utopian to me. Some will, and given time, most will.
