Then why not write the contracts in prolog?
I get that dislodging docx is an impossible job, but since docx is a terrible format for anything, it needs to be done for all the reasons the author mentions. The codes that run society should not be locked up in bad proprietary formats.
This discussion is about contracts, not legal codes. I agree with your statement, but decades now of people on Slashdot being unable to differentiate copyright and patent has made me this way, where anyone potentially mixing up legal concepts has me triggered and jumping down their throat.
