Well, puzzles are made by players, if they don't want to kill puzzles then they should not allow the wand in the puzzle.
I can only agree with your statement if there are natural actuators, but there are not. But even if there were natural actuators, you could only get that by crafting with special materials or by buying after defeating moon lord or so, I don't know, I should have specified a way to obtain it...
See, it is useful, since not every block can be actuated with it, only the blocks with actual actuators in it. If you don't want someone to cheat you can take away the actuator of the block, it is simple, I guess... hahaha
Oh and thank you for helping me improve and deepen my suggestion.
EDIT: Uh, sorry for the doublepost.
