Yes I agree that limiting certain cantrips has nothing to do with balance. There is nothing wrong with cantrips as they are if you like them as they are.
But they can be a problem if you want certain styles of play. Like if you want darkness to matter. Of course then you would also need to limit darkvision. Which I am also for.
So for me this question isn't about balance, but how to homebrew a rule that makes your preferred play style more difficult. And how to do it without just banning it.
As the OP said, it is just utility cantrips that makes their play style more difficult. So how can we limit it fairly without totally taking away their usefulness?
