What will happened if people can fly?

What would happen if people could fly? I for one would absolutely love to have the ability to go all over the world and come back home. Visit anywhere I want. Fly free and go with the wind. Sounds absolutely peaceful and serene. However, hypothetically speaking I think it would be great for some people, but the world would be chaotic and it would cause an enormous amount of problems. People would be killed more while in treacherous airspace of terrorists, there would have to be more laws made for leaving the country without passports, children would have more places to get lost, not only on the streets but in the skies. And someone, somehow, would find a way to extract money from this idea from those of us who don't have the money to take planes, which leads me to think what would we need airplanes for. I guess we may have to take luggage with us sometimes. But there's always con artists and scams and the criminals would have a full reign of escaping and hurting people and worse. I think this is a really fascinating question. I hope you get a lot of responses. These are just my opinions. I'm sure other mylotters might have different views. Thanks for the question.
