This is a weak argument. Many things shouldn't be written in python, because it would the wrong tool for the job. Networking libraries that require bare metal performance, high assurance systems that are easier to write in strongly typed languages.

Block chains solve untrusted writing in the presence of byzantine faults. Not all applications require this. Most don't.

Because the data isn't merkelized?
