You say insider trading is already illegal, so we just need better enforcement. That sounds reasonable—until you look at how impossible enforcement actually is. And that's the core flaw in your argument.
First, insider trading is almost impossible to prosecute. That's why a ban is better. To convict someone of insider trading, you have to prove they used specific, non-public information to make a trade. That means proving intent. It requires wiretaps, cooperating witnesses, and years of investigation. That's why only a handful of cases are ever brought. A ban on individual stock trading is a strict liability standard. It doesn't require proof of intent. You either traded individual stocks while in office, or you didn't. It's a bright line. It's easy to enforce. And it removes the temptation entirely.
Second, your "targeted" approach is a game of whack-a-mole. You want mandatory blind trusts for energy and environmental regulators. But conflicts of interest aren't limited to climate. A senator on the Finance Committee can trade bank stocks. A senator on the Armed Services Committee can trade defense stocks. A senator on the Agriculture Committee can trade agribusiness. The conflict is systemic. You can't target your way out of a systemic problem. A blanket ban is the only way to cover all the committees, all the agencies, and all the loopholes.
Third, your "it pushes holdings into a spouse's name or a shell" argument is exactly why we need a blanket ban. If a public official transfers stocks to a spouse to hide a conflict, that's a violation of the spirit of the law—but under your disclosure regime, it's harder to trace. Under a blanket ban, the rule applies to the official and their immediate family. And if they're trading through a shell company, they're still trading individual stocks. The ban catches that. Your disclosure regime lets it hide in plain sight.
Fourth, your "keeps good people out of public service" argument is weak. Public service is a privilege, not a right. If a talented executive refuses to serve because they can't actively trade individual stocks, that tells you their priority is personal profit, not public service. And there's a simple solution: they can invest in index funds. They can invest in broad ETFs. They can own real estate. They can build wealth just like everyone else. They just can't pick individual stocks while writing the laws that affect them.
Fifth, you want to talk about climate? Let's talk about it. You say a blanket ban is the wrong tool for climate. But the most effective climate policy is a carbon tax, and the people voting on it are the same people who own fossil fuel stocks. A senator from a coal state can buy coal stocks, vote against climate legislation, and profit from the status quo. A blanket ban removes that incentive. It doesn't matter what committee you're on—if you can't trade individual stocks, you can't profit from the policies you're voting on. That's the cleanest fix.
So here's where we are. You've conceded that public officials shouldn't profit from inside information. You've conceded that fossil fuel money in politics is a real problem. You've conceded that enforcement is missing. But your solution—targeted disclosure and blind trusts—is a patch on a broken system. A blanket ban on individual stock trading is the simple, enforceable, and effective solution. It's not a blunt instrument. It's the right instrument.
