CMV: Toilet paper isn't free, why should tampons be?

Pretty simple concept there. Obviously womens hygiene products are essential. But just because something is essential doesn't make it free. Take toilet paper, we all pay for it and use it every single day. No one complains. Or hell, something that is absolutely basic to all life, water. Not free. 

I don't think it has anything to do with sexism or the patriarchy to make women buy tampons or pads. It's just the way the world works. And I believe we should put more effort into making things like food or water free over anything else. 

Full disclosure, just a pretty normal white straight dude. Not a Trump supporter at all. But also not a Bernie Bro. Just so we can get away from the politics side of any ones argument.

I think this one needs more context? Who is demanding free sanitary products for women and why?

In developing countries with a lot of stigma around period blood this can be an important change for girls and women. They are often shunned when on their period and miss out on school/work on these days without access to tampons or pads. So there are many NGOs that work on making these products available for free especially for poorer women. 

In many other countries these products are/were taxed higher than other necessities like your example of toilet paper. 

When using a public restroom you would usually find toilet paper available, sanitary products are less likely to be lying around freely. So this demand of free tampons could derive from this discrepancy.
