I think this is a great idea and write up! I ran similar calculations and had come to similar conclusions in the past thinking it would potentially be a good solution for those experiencing extreme poverty in the US and other high-income settings at the very least. Although, as everyone has pretty much mentioned, they still depend on practical access to private toilets, clean water, soap, and adequate time to wash and reinsert during the day, and UNICEF and WHO both note that many schools globally still lack the privacy and hygiene conditions needed for dignified menstrual management just in general, so it perhaps makes school use workarounds important to iron out?
