Recently, I saw discussions in the group about privacy coins and coin mixing—whether they count as "original sins."

I'm actually more concerned about how I configure my wallet: frankly, the blurrier the compliance boundaries, the more you need to be able to explain the fund flow.

Small amounts for convenience, hardware wallets + backups are enough; losing them is just a matter of regret.
When the scale increases a bit, multi-signature is more like "spreading out single point failures," especially if you're not someone who monitors 24/7.
But don't idolize multi-signature either; if the signer selection, device isolation, and backup procedures are poorly done, it can still fail spectacularly.

I think social recovery is suitable for people who are "afraid of losing mnemonic phrases and can't remember a bunch of rules," but it shifts the risk from "losing it themselves" to the probability of "friends/service providers having issues"...
Anyway, whichever option you choose isn't fate; it's about picking the lower probability among different bad outcomes.
That's all for now.
