What makes it so i have to obey or follow laws

Prosecuted, not persecuted. Apart from your own morality and sense of civilized society, the threat of jail is what makes you follow the laws. You can chose to ignore the laws at your own peril.

you should obey or go to jail... simple as that

Without laws, we'd have anarchy, which would cause uncontrolled violence and suffering. Personal safety (including yours) would be in great jeopardy. Do you want all traffic lights to disappear? Do you realize the deaths and injuries that would ensue? Do you want to omit the law that doctors have to be trained and licensed? Do you want people who have no regard for human life to go around with guns - without any kind of control? Do you want others to judge your religion, or your right not to have a religion? Do you want people to judge whether you are a "good" Christian, Jew or Muslim because of how often you go o to church, synagogue or mosque? Do you want an employer to be able to fire you because you're not of the "right" religion, or because you don't worship "enough?" I'd suggest you take a philosophy class, or at least look up in a dictionary the difference between "malum pro se" and "malum prohibitum." Then ask yourself where we'd be as an individual, as a family and as a society if there were no laws.

Flirting with a little nihilism, are we? Nothing "makes" you follow the laws, including "moral issues." You choose either to follow them or not. When you choose not to, society attempts to persuade you through the criminal justice system and the threat of imprisonment. If the threat doesn't work, imprisonment usually follows. If you reach that point, there will be plenty of time to contemplate deep philosophical questions, like what "made" you disregard law.
