It's tough because sometimes these things can feel like a "tax", i.e. the general public does not need this item so they don't purchase it, but I now have to since there are no longer any alternatives. Seems like perhaps an inconsequential amount for a straw, but it's just another cost most people don't need to consider and shoulder (mobility tools like wheelchairs, maybe specific medicines, etc.). It all adds up.

If cost is an issue, they should be provided by the health care system for those that need them.

But from the other answers it looks like it's more of a problem that they're stainless per se (hard material, need to be washed and carried).
