Because it is highly flammable. it is poisonous and can make a person breathing the fumes very sick, and because it will evaporate if you do and you will have to buy more of it.
An uncovered will will eventually become polluted with dead animals and insects that fall into it. It is also dangerous to humans and domestic animals. Cover it.

Acetone typically evaporates completely, leaving behind little to no residue. If any residue is left behind, it would likely be a small amount of solid impurities or contaminants that were dissolved in the acetone.

They are not hollow- they are filled with a spongy material that is saturated with liquid acetone. When the acetylene is pumped into the tank, it dissolves in the acetone, much like CO2 dissolving in a bottle of soda. If the tanks are laid on their sides, the acetone will be forced out into the hoses and torch. You will get a strange flame with a lot of excess carbon. Tanks that have been laid down should be stood up, and left in that position for at least an hour so that the acetone moves back towards the bottom of the spongy material.
You'd more than likely die. Acetone should not be in the body in any circumstances.
Acetone can be wiped off most surfaces with a paper towel. Any remaining acetone will evaporate. Acetone can be harmful to breathe, so you should ensure that the room is well ventilate. Open all windows to clear the fumes.
It is not good to eat uncovered food because many of the harmful microorganisms spoil the food making us fall ill
