Recently, people keep asking me, "How far can on-chain privacy really go?"

I feel like we should lower our expectations: on-chain isn't an invisibility cloak, more like a glass film that can block the view of passersby, but if you want to pursue compliance, the links, entry points, and exit points can still be traced.
Regular users probably don't expect "complete disappearance," but rather avoiding being exposed and publicly shamed with their wallets fully revealed just like that.

I can also understand the criticism that the staking/sharing security model is just a "copycat,"
It sounds appealing with compounded returns, but layering it on makes the compliance boundaries feel more like walking on tape: it looks stuck, but pull a little and it lifts.
There are many tutorials, but I prefer those that explain "at which step you'll be exposed and how to adjust expectations reasonably,"
Not seeking mystical privacy, just wanting to avoid pitfalls...
Let's start with that.
