Thing is, when using coinjoin you're hiding your transaction history from everyone, including people you may wish to trade with in the future. You can rightly expect to be allowed some privacy in personal dealings. They'll insist on submitted records eventually, I guess.
The thing I have a hard time with is thinking that they will just say, “oh well, the coins went from KYC to a mixer, I guess we lost that trail” instead of filing a law suit and compelling the individual to purger themselves in defense against hidden data collection that proves you either operated a node or donated to a go fund me or engaged in any other kind of commerce deemed illicit.

So uh, don't use a mixer to hide funds that you have to identify to someone later?
There are other uses. It hides the incoming funds' sources pretty well.
Oh, and it's spelled "Perjur," not purger. ;)

I'm surprised my phone didn't autocorrect to purdue or something, not sure where that spelling came from :)

It also seems like wishful thinking to be able to hide a lightning node unless you fund everything from non-KYC coins or fund a wallet in one operation. If you have a regular stream of KYC coins going into coinjoin transactions that then can be correlated into outputs that later open channels for a particular lightning node, you can be sure your meatspace identity is attached to that node through analysis.
