You can get unbreakable items through the use of commands: https://www.youtube.com/watch?v=RQE00wuFPFM

However, entering this command every single time I get a new type of item is a pain in the ass. Then, finding a lava pit or cactus so I can dispose of my old, beakable items is sometimes annoying.

It would be nice if there was a data pack that caused all items crafted by a player to automatically be unbreakable. I could even configure it so that it only applies to items of x quality or higher (e.g. iron or better).
