To claim something doesn’t exist, based on the inductive principle, is to wave away the entire universe with a flick of the wrist as your opening argument.

I would encourage you to read My antirealist manifesto, which argues that reality is a harmful social construct. I'd also like to pre-empt any accusation that antirealism is anti-science, by pointing out My articles advocating for an antirealist future to the application of the scientific method. I in fact believe that any kind of claim to the existence of absolute or objective knowledge is anti-science, and frankly comes uncomfortably close to the inappropriate application of mysticism. You are right when you say that focusing on the tiny chance that we are wrong isn't pragmatic. Which is why so much of My writing focuses on pragmatism as a better epistemological method than empiricism and rationalism applied for the sake of truth over utility. When I say death is a social construct, I am not saying it's a useless idea, simply because it's untrue. I value usefulness over truth, and death is certainly much more useful than it is true.
