Memo to the West: Do you seriously believe your civilisation can last if each of you is critically dependent for your natural daily toilet chores on a specialised product with a complex supply chain and quickly depleting inventory that cannot be easily replicated / localised?
Are you planning to stuff your Mars mission spaceship with toilet paper rolls?
What if this is one thing that has been holding your civilisation back?
The water can be piped and is locally available. The electricity can be wired or transmitted or locally generated. Those are more reliable supply chains, more sustainable dependencies. Your toilet paper dependency is not.
