For the moment I am only trying to gauge people's feelings on this. You have a JoinMarket node running permanently, but others do not.
I am specifically trying to gauge how people feel about receiving a Coin that has been "CoinJoined" VS a Coin that may or may not have a directly "questionable" lineage.
FWIW I probably wouldn't be running my own node if there was a better (quicker, more convenient, not horribly expensive, etc) way to use CoinJoin so you might be onto something here. Wasabi doesn't quite cut it. But I'm not certain that a centralized option is the answer either.
