Holacracy Community of Practice Archive, 2015-2019 Community Holacracy Web Site

could it be that the only purpose of some organisation is to not exist?

My answer is no - and may be I'm wrong - For me the Purpose of an Org. is the deep reason why it exists from an evolutionary perspective. So, as one Org. exists, it has a "Raison d'être".

P.S. Or, perhaps, a company culturally isn't ready for Holacracy adoption, and if you never stop it will eventually go bankrupt?

Different subjects for me behind your question. As I like to say Holacracy is not for everyone, every Org. , every culture. 

And re going bankrupt, we've a case of a company we've helped implemented Holacracy some years ago that went bankrupt.  They would say and I agree, that this was not due to Holacracy adoption.
