That is short. Arithmetic supports material (appearances), but here you seem to 
say that a substrate would support some primary matter. The physical accounts 
for the Material in non physicalist theories too. It is just that the 
“material” appears to be a mode of the observable, definable from 
self-reference.

But then why criticise my use of it against physicalism?

Then I am not sure we have disagreed.

Same here.
