My argument is the same one that Bell, Kochen, Specker, Conway, and so many others have covered before: If photons were locally real, then we'd see different measurements from what we actually do see. The video covers the basic idea of witnessing this using polarizing filters, as well as explaining Bell's inequalities using basic discrete set theory and Venn diagrams.
We don't have to lose reality; we could instead lose locality. However, then we also lose most of physical causality and spatial relevance. [0] covers all of the material but takes more than 20min to read. At the end of it, we're left with a very weak theory that has trouble ruling out FTL influences.
On the second point, it doesn't particularly matter whether those natural laws exist; my point was that they're not fully knowable. There's no reason why the universe ought to admit a short legible encoding of its own structure, especially considering that such structure ought not be observable by creatures like us residing in the universe.
Rather than knowing the natural laws, we know predictive models which are good approximations. There is fundamental uncertainty preventing our approximations from sharpening to some arbitrarily fine precision.

- AnimalMuppet 6y agoYeah, losing locality instead of reality was what I was referring to. Although that would be pretty weird too. But losing one or the other, and not knowing which one, is really uncomfortable. That leaves us with your comment about quantum disproving the first two points... well, I can say that it's not proven yet, but I also can't say that you're wrong.
- ncmncm 6y agoI have long since given up on locality, and so have come to resent the persistent need, every time I move, to force my stubborn body to traverse every Planck length between here and there. The apparent knowability of the universe, until recently, has always been its most astonishing feature. We should not be surprised to find limits on that; nor that we have not yet actually run up against those limits.
