The concept of vaccines had been known for centuries during the 1940s. No one had ever gotten a polio vaccine to work. Imagine if they had concluded since it had never been done that it therefore could not work.

We are aware of remote viewing as a concept but it does not currently exist - no one has ever gotten it to work. There are very good reasons to think it can't work, but the lack of a practical implementation alone is not such a reason.

The issue is not capitalism specifically, it just frequently takes that form. Firefighters not doing something is equally fallacious proof of impossibility.
