This is a pretty click bait title. Banning congress people and their families from trading any stock altogether is pretty extreme. There are laws against using material non public information in trades that are clearly being violated and these laws should be enforced and strengthened. An outright ban is a bit of a big imposition. Creating narrow trading windows, or requiring trades to be pre-planned are both reasonable approaches, but the article focuses instead on the most extreme form of restriction and ignores any of the more reasonable reforms.
