Am I correct in assuming that swapping into and out of lightning or even just performing a single-hop tx from the mix address subvert this horseshit? nostr:nevent1qqs2ys6enr8k7zcjz3cnqccs630eqdsd03nu2n0c2ayy4m0lw06ktksprdmhxue69uhhyetvv9ujumn0wd68yurvv438xtnrdakj7q3qqny3tkh0acurzla8x3zy4nhrjz5zd8l9sy9jys09umwng00manysxpqqqqqqzndknuj
you're correct
IMO, adding an extra hop is an obvious transaction pattern and the next step is a rule against that. But yes, these are work arounds.
I remember back in the day, before easy mixing, to wash coins, I used to move a balance to a gambling wallet, play a little, and then withdrawal. To effectively execute this, FINCEN is literally going to have to create a rule where you can prove above-the-board provenance for the entire history of a balance, and even then, there is lightning.
