Single use bendy straws were literally invented to help keep bedbound and other disabled people alive. There are also many reasons people can’t use different alternatives.

You personally not using something, doesn’t mean others don’t, and to deny access to a literal lifeline for the sake of 0.003% of the plastics in the ocean (literally a drop in an ocean) because it makes you feel better and requires zero effort or sacrifice (from you), instead of actually acting to resolve the problem (like being anti-capitalist rather than just trying to apply band aids to its symptoms) is not only gross and ableist, but also a colossal counterproductive waste of time.

There is a lack of non-plastic materials that are suitable for every disability while also being affordable. This chart lists common problems with non-plastic straws for some people.

Complete plastic straw bans have a poor reward to risk ratio. It fixes almost nothing while putting some disabled people in danger. Just make it mandatory for restaurants and fast food to only give them out on request instead of by default and that will cut down on a huge portion of the straw waste while keeping them available for those who need them.

I’m not in disagreement regarding moving away from disposable goods, especially plastic based ones. Just trying to point out the problem isn’t as cut and dry as you suggested. Straws are popular partly because they are more accessible so any solution that involves getting rid of them should take that need into account.
