As witcher_sense has pointed out, you can spin up your own coordinator if you wanted and as others have done, but a complete lack of liquidity will mean you can't actually coinjoin anything. If you want to use coinjoin right now, then JoinMarket is the best option.
Darn it. I completely forgot about liquidity. It's not like anyone wants to put their personal funds on the line to run a coordinator.
This is sympthom of a greater problem where the BTC community is gradually being split up into two factions of
whales and everyone else, and people are finding out that the whales are the ones who can create exchanges, mixers and coordinators (assuming there is no 3rd party VC involvement which I will ignore for this analysis) and when these services get stung, we can't make alternatives because we got no liquidity of our own.
