IMHO, it could be used as a load balancing device for a system with a fixed block size limit. CoinJoins happen automatically to help compress more transactions into the available block space. This could provide a good argument against a scheme with a continuously variable block size, or to a scheme with no limit at all (although I don't think anyone has yet made any serious proposal for the latter). It also illustrates that CoinJoin really is just that, joining inputs and outputs into single transactions, regardless of the utility you're seeking from doing so.

Interesting. What is the effective 'compression' of doing several individual TX versus a single CoinJoin containing the same TXs?

There's a fair proportion of header/data for single output -> pair of outputs, but mamadmankan is only identifying the first steps in the line of thinking that led to stuff like SegWit and Lightning.
