I totally get putting the foot down if there were substance abuse or violent outbursts in the mix, however, if I am reading this right, you are saying that this is not the case with your relatives.
Since this is NOT the case with your relatives, your wife has no ground to deny you and the children the right to see their family.

You are reading it right, there's no reality-based reason to think the children would be harmed by interactions with my relatives. In her reality, it is a different case.
Forcing this issue seems to require one of two things. Either I argue that I have the right to take the children because she is delusional. Or that I ignore arguing and the question of who's grasp of reality is the sounder one, and just declare that I have the right to have my way and walk over her in this.
I don't expect any positive outcome from telling anyone they are delusional, especially when she goes out of her way to deny there could be anything wrong with her.
So it seems I'd need to stand firm in the knowledge that I know better, act accordingly, and ignore her twisted thinking. The thing is, that requires me to take away her agency to keep her children safe to the best of her ability. That's a horrible thing to do to a parent.
What is she going to do to stop you? She has no legal right to do so.
Whatever she can, I think. I can imagine her standing in front of the door to stop us from leaving, hiding the car keys, holding our son's hand so I can't carry him out, forbidding me using the car (it's not mine), screaming at me so that if I manage to leave, it's with a terrified crying toddler who wants to go back to mommy... Who knows what would actually happen.
Also, probably, making my life as much a miserable hell as possible for the week or two afterwards as a promise of what will always happen if I ever dare to do it again, and making it clear to our son that I did a horrible thing in taking him, and that it's an awful thing to do to go and visit those people and he shouldn't go along with it.
Barring physical attacks, what are you afraid of? Making her mad? It sounds like things can't get a lot worse. What do you have to lose?
Mostly it's the children getting caught in the middle that horrifies me. By now I can handle all sorts of things directed at me... And if she breaks down completely and ends up in psychiatric care, that might even do some good, who knows... But involving the children, now that's something else.
Oh, and things can always get worse.
