You are defined a 3D universe, by how? Length, width, heigth. A basic understanding. You do not have things turn into the liquid form, and becoming a human heavy silver metal color. You do not born in a world that has that kinds of definition, and therefore, you do not force the humanity to believe in those reality. You have to be born in it believing that gravity to fly.

You trying to impose some ideas through the Movie, that is not the physics laws in this world.

The physicality of all around you its when you open your eyes and see, and feel.

The physics laws of that defining all those attribute like heat, too hot burn, you having a first degree burn, you have a nurse or doctor to attend that wound in some procedure that given to the clinic, or the hospital format. 

Those are step by step. People got panic, if something like that happened.

You educate people not to do certain things, so those ideas do not come to them.

You cannot outlaws certain things "Its translucent, SO COOL!" you are born in it, you do not impose that the rest of the humanity to accept that with a consequence label, or told, or learn from. Some of those ancient doctrine should be endow and in mind.
