Issue one: The government should not have the right to issue a higher tax on carbonated drinks/soda to discourage teen obesity because it would be not alter the demand for these types of products. Say for example we use the supply, demand, quantity and price model, supply and quantity are unaffected in this model, whilst price goes up. When the price goes up, this would be an example of where demand does not decrease since the price would not deter people from purchasing it. With the amount of sodas that have to be regulated and how common they are to the everyday life, it'd be a waste of time. Furthermore, it is not the responsibility of the government to regulate personal choices done by the customers, it is their own choice if they choose to be healthy or not.
Issue two: The government does not have the right to monitor our actions on the internet to keep the nation safe from terrorism. The internet is a free market, a public entity supplied by public cooperations and access given by ISPs. The government's jurisdiction does not give them permission to monitor the internet as it could possibly fall under a violation of the fourth amendment. The ISPs, social media networks, and any other cooperation has the right to monitor actions as it'd be written out and agreed by the user in their terms of service, the government should not have involvement, only their intervention is required when a report is filed.
Issue three: The government should be allowed to outlaw texting while driving since it is a hazard to personal safety and the safety of others. The roads in the United States of America are mostly public, and texting while driving impairs the user's ability to react to incoming situations, whilst taking their focus off the road. Similar to drinking while driving, it only becomes an issue when the safety of others aside from your self is put at risk. In which case, I do believe the government has the right to outlaw texting while driving to keep drivers safer on the road.
