It’s always a matter of perspective, yet in the end it doesn’t make a difference, you’re making a choice over some arbitrary distinction. If this container were just mildly rusty, no one would balk at using it for water, yet rust would be just as dangerous to congest in the end.

Sorry the entire premises you’ve based the argument on is entirely flawed, there is no huge difference. It’s I don’t understand the principles at play, so I’m gonna make arbitrary distinctions to make myself feel better.
