Again, it simply highlights that your crafting system is pathological. If you are going to find and carry around your ore in such bulk quantities, then you should either be able to procure it easily on the spot (so buy or find it locally as needed) or not have it tracked at all, just the rare ingredients.
It sounds more like you're against the way most crafting systems are designed rather than making a solid argument against unlimited crafting resource carrying. Whether you like it or not games like Witcher do require a bunch of random bullshit that isn't right there at the crafting bench all the time, so if you had to store the bullshit elsewhere it would just create hassle for no gameplay benefit. My core point is I want unlimited crafting materials carrying in those games. If you designed a game where only rare ingredients mattered, then it would be a different story.
