I agree so much. See also "laws without laws" by J. H. Wheeler.
There is an interesting (but wrong IMHO) answer by Deutsch.

Deutsch present his "Church Turing principle" as a physical version
of Church's thesis. This is terribly misleading even for someone who
believe that physical science is fundamental.
>From now on I will always say "Deutsch thesis" for his "Church Turing
principle". Deutsch thesis is intrinsically very interesting but is
completely independant (a priori) from Church's thesis.
I suspect that Church's thesis could very well entails the falsity of
Deutsch thesis.

Remember that with Pure COMP (as opposed to Mallah's Physical COMP), in
some sense Psychology is O-order and particules Physics is very
high-order.
