You're right that most officials aren't crooks, and punishing actual misuse sounds fair. But that's the fragile part. Proving intent is nearly impossible, and by the time you catch it, the damage is done. A ban is a simple circuit breaker. No individual stocks, just diversified funds. It removes the latent option, the temptation, and the appearance of a rigged game all at once. We don't wait for every driver to prove they can handle a racecar on public roads. We set a speed limit. Skin in the game should make public service the bet, not a side trade.
