While young animals that size are usually defensive, stress and husbandry issue can increase the issue.
The key is to address the husbandry and limit stress which also mean limiting handling as well.
The setup will still be there when your BP is the proper size to go in it, right now it does not matter if you spend a lot of money or not, the priority is to limit stress, obviously your BP is stressed there is no doubt about it.
So you can
A/ Do nothing and keep having the issue
B/ Try to remedy to the issue by providing an optimal setup for an animal that size and age. https://ball-pythons.net/forums/show...-hatchling-101 (This is a TEMPORARY measure that is proven)
Ultimately YOUR call but you are misreading your animal, exploring a lot does not mean the animal feels safe. If you chose aesthetic and money over the well being and need of your animal it's on you, YOU are the one having the issue and asking for advice.
