No, John, science doesn't follow rules that you make up for science to 
follow. Why should it follow rules you make up?

And just because YOU can't explain it using incorrect macroscopic
concepts doesn't mean it's wrong. It means you're wrong.

The purpose of science is to figure out the rules nature actually uses
so we can model nature. Science often finds a few unexpected surprises.

Point particles are just one reason why trying to think of QM spin as being
little thingies rotating is wrong. It doesn't apply there. It doesn't mean 
point particles is a wrong concept, it just means thinking of QM spin as a 
rotation of a tiny ball is wrong.  Yes, macroscopic spin is meaningless,
but QM spin isn't meaningless.

Consider this: QM spin is quantized - you don't see that with macroscopic
spin. It either isn't or the amount is so small it can't be measured.
But the biggest thing is the very different behavior of things with the
quantity equal to an odd number of hbar/2 units or an even number of
hbar/2 units. Explain bosons and fermions simply by rotation of little 
balls. You can't.
