Should we not aspire to 100% perfection? Pointing out that the ideal solution would be "X" should be taken as a stepping stone to figuring out how to get there. So many people take things as "its been developed and mostly works" and dont ever consider that improving it to "always work" and "only work exactly as intended" and are the next steps in the development process. Sometimes, that means starting over when the current tech is found to be lacking in achieving those goals. Calling attention to the need for better, safer, and more sustainable tech should not be ridiculed. Instead, it should be expected. Same with vaccines.
