The government needs to set such rules because government's role is to protect the common good of all. If one person gets sick from communicable disease or poor sanitation, that person can spread disease to others. In addition, it is usually the public who has to pay for the effects, not just one individual. The public pays for the spread of disease through higher insurance rates and paying the cost of cleanup. Prevention is much cheaper than cure, and the best prevention is through education and regulation. Regulation is needed because education is not enough to guarantee that individuals will do what is in the best interest of everyone, or even what is in their own best interest.
