That’s a good short term solution but long term you just screw your kid up.
There’s some things you simply cannot do, and nothing else can be done about it. You have to learn the lesson that sometimes you lose a conflict and that’s it. You don’t get anything else. Sucks? Yea welcome to life.
It's a tool in the toolbox, not the only tool. Kids need to have some level of agency over their lives. They also need to know that there are some things you can't just do. Negation comprehension doesn't develop in most toddlers until roughly 27 months, so it's also a matter of what is age appropriate.
The question is what is the right age to learn that lesson at.
Any age. There is no right age to jump out of the window on the 10th floor, no right age to cross a busy interstate by foot, no right age to set a bed on fire. You wouldn’t allow a kid to do it (and similar things) at any age. Would you? :)
