Exactly, that's where my mind went too. I think people are tempted by a well-meaning skepticism to think that it's high minded to be skeptical of affirmative claims of knowledge, but it ends up throwing a very hard won model of everyday physics out the window.

I saw a very frustrating live "debate" between Dr Blitz (monikor of a really cool science communicator and irl PhD physicist) and a flat earther, where the flat earther essentially borrowed these arguments (eg observations aren't really predictive or generalizable or able to count in favor of specific theories, confirmed theories have no special status etc) to dismiss the evidentiary support of the earth being round. It's an intellectual car crash masquerading as a respectable position on scientific foundations.
