Make sure he understands the principal behind the request. You are not asking him to refrain from destroying something, you are teaching him to respect your decisons and to value their importance. Because later in life, it is only going to get tougher.
Maybe you can all have a sit down family meeting discussing each other's roles in the family and how you can all show respect for each other.
We had this type of meeting every Monday night, we went over our chores for the week, or schedules, we read some scriptures, had a little family activity, had a dessert, and we all talked about things we needed to improve on and we all also got told what we were doing that others were proud of.
Its a good way to keep every one in check and for kids to understand who the authority in the house is, as well as feeling valued at the same time.
