Why is there no natural syntax for accessing attributes with names not being valid identifiers?

Im not sure what you are saying.
Sure a language designer can design a language differently from python.
I mentioned lisp. Cobol is another behaving exactly as you describe.

My point is that when you do (something like) that, you will need to change the
lexical and grammatical structure of the language.  And this will make 
for rather far-reaching changes ALL OVER the language not just in what-follows-dot.

IOW: I dont agree that we have a disagreement :-)
