The problem with this is the quiet nihilism baked into it, which is the same reason so many people believe that widely supported science could be wrong.
In the absolute sense, it is true. Though things like “the sky is blue” is more about linguistics, but for a layperson it’s kind of inconsequential either way. While there is a small possibility that scientific consensus could be wrong, there is orders of magnitude bigger chance that unwarranted skepticism is dangerous. Reality does exist, regardless of how much epistemology you choose to wave away.
Visually it is exceptional, but I fear it is too dry and thin to make an effective walking stick or tool handle. Maybe for smaller hand tools like a screwdriver.
