In the anime, manga, and games Pokemon are captured and stored in Pokeballs. Can Pokeballs be used to contain anything else, e.g. inanimate objects or people? If you can pop a 999.9kg Celesteela in your pocket (not to mention store it digitally and transfer it between Pokemon Centers), it seems like that same mechanism would be used for storage, shipping, whiny children in need of a time-out, or a myriad of other purposes.
In the games, any visible item lying on the ground appears to be in a container which at least has a shape similar to a pokeball, (though this was likely done for graphical reasons in the early titles). Other than that, I haven't seen them used for anything other than Pokemon.
Based on this answer, it appears that only Pokemon (or items containing Pokemon) can be trapped. So, are there canon reasons why Pokeballs or the same technology can't be used for other purposes?
Not a duplicate - I'm asking for specific canon reasons - from manga, games, or show - why it can or can't happen, not examples of when it didn't work or didn't happen.
