It's amazing how so many anti-bin posters lack any empathy for other people.
It's now all about you. (As in the first post by the OP.)
It's about your visitors.
How you can be so sure that they don't need a bin, is laughable.
Women use protection at all stages of their life, from panty liners if they have a lot of discharge, to periods, to 'leaks'.
How you know that your visitors don't use these and might need to change them is showing the limit of your imagination.
I've been to houses with no bins and had to wrap STs or liners in loo roll and take them home with me.
Surely it's best to work out in a thoughtful way what other people might need? My bathrooms have bins and also a pack of panty liners in case any visitors (sons' partners etc) get caught short and need something.
It's just good manners, accommodating visitor's potential needs.
