Another silly attempt to discredit libertarianism…
There are gazillion things that harm your body. Government regulates very few of them. Sugar is the most lethal substance in US. Do you want government to ban sugar? Everybody knows sugar is not healthy. Every fat person knows they might die early because of their eating habits. Do you want government to control their lives?
Do you also want to shut down McDonalds, Burger King, Subway, Wendy’s, Taco Bell which sell unhealthy products and prey on those fat people? Ask those people, waiting in the line to get their products. They know they are eating unhealthy. Do you want government to force those people to drink smoothies?
You want government to ban things you don’t like and you don’t prefer to do. When government steps in to ban things you do, you cry like a toddler.
