Is producing plastic bottles for water, or straws for people with mobility problems, only for emergency possible?

Edited:
If there isn’t enough demand of an item, it would be too expensive it doesn’t get produced, in general, right? So bottled water is needed for when the tap water is undrinkable, and straws are needed for the people with mobility issues. So, what happens when these items (for example) get banned? How do companies produce them without losing money? I mean they would import them from the closest city, but what if when it get’s banned everywhere?
