Much later Ernst Mach proposed that all the matter in the universe causes the inertia of local objects. Mach even suggested that if Newton's bucket of water were at rest and the universe were rotated about it, the water would form the same meniscus as when Newton rotated the bucket. It is surprising that Mach did not realize that if the Earth rotated around the bucket, let alone the whole universe, no mere meniscus would have been formed. The strongest tidal force imaginable would have emptied the bucket.

Why is that so surprising? Mach didn't realize it for the same reason that I don't "realize" it: I don't see any reason whatsoever that it should be true.

If distant bodies caused the inertia of a body, we should expect nearer bodies to cause directional variation in that inertia.

"We" don't necessarily expect that. If you look at the theories, and look at the astronomical maps, and do the calculations, it turns out not to be true. Your arguments are based upon your personal fallacies.
