I think it's very important to note that it's actually impossible for everyone to run their own coordinator.
Certainly not with Wasabi. With JoinMarket, then effectively every taker is indeed their own coordinator, and so it becomes impossible to censor any individual user (unless you controlled every other UTXO in JoinMarket, which will obviously never be the case).
And they're only getting better. Bisq 2 is right around the corner, which apparently also includes Lightning functionality.
Now this is interesting. Last I read it was very much still in the "exploration" stages:
Lightning Network based 3-party trade protocol
Unclear if this is feasible yet, but it's very interesting.
Can't wait to see what format it takes!
