Mage hand is the kind of spell that is incredibly useful and dynamic in actual ttrpgs, and incredibly difficult to design around in a video game.
A GM is going to consider the distance and weight limits of the spell, and determine of it makes sense of not. If you stole The One Ring from Frodo, for example, the GM can pivot and make the world react to that.
The video game has to program all possible uses of the spell while also trying to keep a prewritten story on track. If you steal The One Ring from frodo, the game would have to reinvent the plot dynamically, which isn't really possible. The end result is that they have to severely limit the uses of Mage Hand.
Because Mage Hand is so potentially chaotic, it can't be as useful as it would seem. The same would go for the spells Fly and Invisibility. Imagine the Black Gate of Mordor. If there was a level 6 wizard, they could use fly + invisibility to get everyone safely over the wall. Now, sure, it would take a while waiting for spell slots, but this is supposed to be the most fortified pass in the entire world. Even GMs have problems with this. Suddenly every remotely secure area needs a mage on staff detecting intruders, or permanent enchantments. At that point, Fly might as well not exist.
Edit: I forgot that fly and invisibility both require concentration. Oops. Still, now you only need a level 6 mage and a level 4 mage, which is still pretty easy to pull off.
Magazine size laws aren't really effective at doing anything. Up in Canada you can't have a rifle magazine with more than 5 rounds. However, almost all of the magazines are full size magazines that have been modified to hold fewer rounds. All of the responsible owners leave them at 5, but with a minute or two of work you could turn most of them into full size again. We don't have mass shootings every day.
