ELI5: Legally, if we have the right to bear arms, why can't we own bazookas, machine guns, anti aircraft guns etc?

In most states you can, it requires a Federal and State firearms license, and if you do enough selling or trading a business license. Most people who do own heavy weapons tend not to advertise much to avoid being ripped off or having a demonstration 24/7 on their lawn. But bazookas and many AA guns are considered antiques as well as fire arms, making them even easier to buy.
