If UFO Anti-Gravity, or Free Energy technology existed on Earth, it would be highly illegal. The reason for this is that the knowledge of the technology, if learned, would destabilize society. After all, forget the implications of what free energy would do to the economy. Every product, business, lifestyle is somehow dependent on fossil fuels. Taking it out of the picture would be devastating to society. But that's a whole story on it's own. Instead just think what having anti-gravity devices would do society. Roads would be obsolete. The skies would be chaos. You couldn't limit where people could go. Property couldn't be protected. Imagine what it looked on the fictional Star Wars planet of Coruscant (pictured.) Our cities just haven't been built for this type living. Think of prison yards, rooftops on banks and stores. Fences would be meaningless. Conspiracy theory or not it's clear that the government couldn't let the free energy or anti-gravity tech exist in the hands of the public. Not for a thousand years without slow incremental changes.
