Good attempt to fix the discussion in your favour by asking people to treat the proposed ban as a joke in advance. But I'm afraid you are wrong.

From the UK Food Standards Agency web site:

Eating too much salt can raise your blood pressure, which triples your risk of developing heart disease or stroke.
• Coronary heart disease is the most common cause of death in the UK, with about 94,000 people dying each year.
• Stroke is the third biggest killer and a leading cause of severe disability in the UK. More than 250,000 people live with disabilities caused by stroke.
• In 2006, about 55,000 deaths in the UK were caused by stroke.
You can reduce your risk of heart disease and stroke by cutting down on salt, eating a healthy diet, being active and maintaining a healthy weight.

It's no joke.
The good news is if you give up salt everything is flavourless for a week then you stop noticing and start tasting the food.
