Arsenic would kill you immediately. There is no evidence to prove that trans fats will kill anyone immediately. There is little evidence to show that trans fats are more or less deadly than alcohol or tobacco. Arsenic is a deadly poison that will kill in small amounts.
That being said if a restaurant put arsenic in its' food people wouldn't really eat there, would they? Even without government regulation it would go out of business pretty quickly.
You can't champion the removal of trans fats when you're happily sucking on a cancer stick or chugging a beer.
Just because you enjoy the sensation those two give you doesn't mean they're any less harmful for you than trans fats.
And again, it's your choice to not eat healthy meals you prepare yourself. Your life is busy because
you have decided to make it busy. Unless you're military or in prison you have the freedom to prioritize these things and you have chosen to place social interaction above cooking for yourself. You do have the ability to eat a home prepared meal every single day. You choose not to.
