I never said nature was absolute. It can often be ambiguous and go into two directions, but, if it ever forms a solid leaning towards something, it's impossible to ultimately counter. For example, take flight, you cannot fly infinitely on your pokémon, as they become tired and return to the ground. Aircrafts and helicopters require fuel to propel themselves, otherwise they're pulled back down to earth and obviously people cannot fly period. Even though these all provide temporarily relief from gravity, they still ultimately have to adhere to it.
