If the wave function is real, and not merely a tool that yields right
probabilities for us, then the superpositions within the wave function
would all have an equal claim to reality.

This is kind of what I meant, if the container is large enough, the
discrete nature of the fluid will eventually break down. E.g. a system of
pies, each of which splits into two pipes every foot, and if this goes on
for 1000 feet.

Then what resources is the computation using? We can agree we get the final
answer and it is not by magic, so clearly something real is responsible for
yielding the answer. According to the theory, this thing is the wave
function, and the resources used are all of the wave functions various

There's nothing to motivate this theory.
In fact, there's been no reason to believe in Copenhagen Interpretation
since Everett used the assumption of no collapse to show how the math of
the theory produces the illusion of collapse. You can't get a more clear
cut case for Occam's razor's preference for MW over CI than this: explains
more, while assuming less.
