yeah what is up with that? I remember going to Michaels for some stuff and they had all the paint like locked up, I laughed at them when they came to open it.
It's like that everywhere. Some things are too dangerous to have out on the shelves while two towns over those are fine and something else is too dangerous. If you try to figure it out you will just hurt yourself.
In MA you can't buy beer at the gas station, ammo is locked up, but spray paint is out in the open.
In TX you can buy beer at the gas station, ammo is on the shelf, but spray paint is locked up.
You can't rent a car if you are under 25, but U-Haul will rent you a giant truck with questionable brakes at 18.
I have even seen it vary across stores in the same state. Western New York I could buy .22LR off the shelf all day long. Eastern New York .22LR was locked up behind the counter and I couldn't buy unless I had a pistol permit from NY State.
