I do not agree.

(This is why we do never agree on anything.)

I actually think, that models and reality are two distict entities.

Models are useful, but nature is not.

Nature is as nature is and that is not supposed to serve our demands.

To make calculations possible we use simplyfied versions of the real 
world, call that 'model' and let them run in computers.

But that is NOT how nature functions, not even close.

If we want to understand nature, we had to give up our demands for 
usuable models, because we can safely assume, that nature itself does 
not use computers.

I do agree here and did already (even if GR had a slightly different title).
