"Enforce the laws we have" assumes the laws work. They don't.
The STOCK Act's disclosure requirement is the current answer to "just disclose it," and it's been a joke in practice. Late filings are routine, the fines are often just $200, and disclosure only tells you what happened after the trade already occurred. Disclosure catches insider trading the way a security camera catches a burglar — after the house is empty. A ban prevents the act; disclosure just documents it for a news story six months later.
The driving analogy inverts the actual asymmetry. Texting drivers can't see other drivers' texts. Officials trading stocks routinely have access to information that moves markets — pending legislation, classified briefings, regulatory timing — that the person on the other side of their trade doesn't have. That's not a comparable risk profile to ordinary driving; it's closer to letting casino pit bosses bet on the tables they're supervising. The concern isn't hypothetical texting-while-driving risk, it's a structural information asymmetry built into the job itself.
"Only a few members sit on relevant committees" undercuts itself. If the informational advantage really is narrow, a ban costs almost nothing — most members claim they don't trade on inside information anyway, so giving it up should be trivial. The louder the objection to a ban, the more it suggests trading is more valuable to more members than the "it's only a few bad actors" framing admits.
Blind trusts are a red herring, not a real concern. A true blind trust (independently managed, holdings undisclosed even to the official) is precisely the transparency-preserving solution here — the public knows the structure is blind, even if they don't know the daily holdings, which is a trade worth making. The realistic alternative isn't "opaque assets we can't see" versus "transparent stock trades we can see" — it's officials being legally barred from acting on privileged information at all, versus the status quo where they can act on it and merely have to mention it in a filing later.
"Performative purity" is doing a lot of work to avoid the actual data. Multiple studies (Georgetown, and separate academic work on congressional trading) have found members of Congress and their spouses outperforming market benchmarks over years — not by rounding errors, but by margins that are hard to explain as coincidence at scale. That's not vibes; that's the empirical basis for the policy.
The steelman against a ban isn't dead, though — it still has good points worth weighing: talent recruitment effects are real, enforcement of any new rule (including a ban) still requires political will that's currently lacking, and "blanket ban" proposals do vary a lot in whether they cover spouses, dependents, judiciary, etc. — scope questions the disclosure-only side is right to flag as unresolved.
