It still seems to me that consciousness itself could be an argument against 
a purely information-based ontology. ("Information" meaning based purely on 
numbers, combinators, etc.)

Philip Goff and Michael Shermer discussed basically this:

https://scottbarrykaufman.com/podcast/solving-the-mysteries-of-consciousness-free-will-and-god-with-michael-shermer-and-philip-goff/
 

via  https://twitter.com/Philip_Goff/status/1043053992916467714

(In there there is an about 1 hour podcast.)



My summary (fits in a tweet) of Goff:

"Physicalism, based on pure informationality (quantitative states and 
language} is not sufficient to explain consciousness,  but a materialism 
(one greater than physicalism) that is based on experientiality 
(qualitative states and language) in addition to informationality, may be."
